NeoOrigins Power Types Reference

All powers share six optional top-level fields:

Field	Type	Description
name	string or {"text":"..."} / {"translate":"..."}	Display name shown in the origin selection screen. A plain string is treated as a translation key.
description	string or {"text":"..."} / {"translate":"..."}	Description shown below the power name. Same resolution rules as name.
hidden	bool (default false)	When true, this power is excluded from the origin info panel. The mechanical effect still applies; only the display row is suppressed. Useful for purely-internal flag/glue powers (e.g. neoorigins:toggle, on-hit setters wired under a multiple).
required_mods	list of mod ids (default [])	Load gate: the power only loads when every listed mod is present. Use it for content that targets an optional mod (e.g. the built-in Dragon Survival dragon forms carry "required_mods": ["dragonsurvival"]). Origins accept the same field. See PACK_FORMAT.md.
power_condition	entity condition object	Runtime gate: the condition is re-evaluated against the power’s holder every time the power would act, and the power only operates when the gate is satisfied. Works on every power type. See the universal power condition gate section in CONDITIONS.md for details and the condition format.
power_condition_mode	"ALLOW" or "DENY" (default "DENY")	How power_condition gates: ALLOW = the power is active while the condition is true; DENY = the power is disabled while the condition is true. Case-insensitive.

condition as an alias. On power types that don’t have their own condition config field, a top-level condition is accepted as an alias for power_condition with mode ALLOW (so the power is active while the condition holds, the intuitive reading). Notes:

• These types claim condition for their own config and are excluded from the alias: model_color, attribute_modifier, action_on_event, modify_damage, active_ability, active_dash, persistent_effect, condition_passive, effect_over_time, creative_flight, restrict_items, prevent_death, conditional, particle. On those, write power_condition for the whole-power gate.
• An explicit power_condition_mode is honored even when the gate comes in via the alias.
• If both power_condition and an aliased condition are present, power_condition wins and a warning is logged.
• Prefer power_condition in new packs; the alias exists so the common Apoli-style spelling doesn’t get silently dropped.

enabled: the per-power kill switch. condition_passive, creative_flight, model_color, persistent_effect, pose and water_breathing accept an optional top-level enabled (bool, default true). When false the power stays attached to the origin but does nothing — no effects, no flight, no periodic action. It exists mainly so a server owner can drop one power out of an origin from config/neoorigins/power_overrides.toml without editing the datapack, but a datapack may write it directly.

Action & condition fields take an object or an array. Wherever a field below holds an action (e.g. entity_action) or a condition (e.g. condition), you may pass either a single object or an array of them. Action arrays run in order (implicit neoorigins:and); condition arrays must all pass (implicit AND). An empty array no-ops for actions and is always-true for conditions. See ACTIONS.md and CONDITIONS.md.

If neither name nor description is present, NeoOrigins falls back to the lang key convention: power.<namespace>.<path>.name / power.<namespace>.<path>.description

Cooldown HUD fields (active powers). Every cooldown-gated active (keybind) power type (active_ability, active_teleport, active_dash, active_recall, active_swap, active_fireball, active_bolt, active_phase, active_place_block, ground_slam, tidal_wave, command_pack, elytra_boost, mount, shadow_orb, summon_minion, tame_mob, loot_pool_grant) additionally accepts three optional HUD fields. neoorigins:js_active is the exception on this version: it reads only js_id, cooldown_ticks and hunger_cost, and ignores these three:

Field	Type	Default	Description
cooldown_icon	string	""	HUD cooldown icon: an item id (e.g. minecraft:ender_pearl) rendered as the item, or a datapack texture path ending in .png (resolved under assets/<namespace>/textures/, e.g. mypack:gui/fireball.png → assets/mypack/textures/gui/fireball.png) drawn 16×16. When set, the HUD swaps that slot’s cooldown bar for the icon with a clock-style radial sweep (dark fill over the not-yet-recharged arc, wiping clockwise from 12 o’clock). Empty keeps the plain bar.
cooldown_countdown	bool	true	Draw the remaining cooldown in whole seconds translucently on the icon. Only applies when cooldown_icon is set; players can suppress all countdown numbers with the show_cooldown_countdown client config switch and tune the text opacity with cooldown_countdown_opacity.
always_show_icon	bool	false	Keep this power’s icon on the ability HUD cluster even while it is idle / off cooldown (full-bright, no sweep, no countdown). Only applies when cooldown_icon is set. Note: this is what makes an idle icon persist under the default client HUD mode (hud_ability_display: COOLDOWNS_AND_TOGGLES), which otherwise shows a non-toggle icon only while it is recharging. Under ALL_ACTIVE_ABILITIES every icon-bearing ability already keeps a slot, so the field has no additional effect there (players can also force all icons on with always_show_ability_icons).

Toggleable powers (flight, creative_flight, item_magnetism, no_mob_spawns_nearby, phantom_form, stealth, wraith_phase, plus persistent_effect, condition_passive and effect_over_time when authored with "toggleable": true — effect_over_time is also toggleable under "activation": "active" — and pose, which is toggleable unless you set "toggleable": false) also accept cooldown_icon and always_show_icon. A toggle with an icon joins the HUD cluster: full-bright while toggled on, dimmed while off (no cooldown sweep).

A toggle no key can reach comes back on at login. Toggle state is saved with the player, so a toggle switched off stays off across a relog, which is only safe while some key can switch it back. Outside the class layer the six skill keys go to the player’s first six active powers; the class layer has the single Class Skill key, held by its first active power (see CLASSES.md); and a power with its own key binds to that instead (see API.md). A toggleable power left over after those slots is still granted, but the player has no way to flip it, so at every login NeoOrigins clears its off state and it runs as switched on. That includes a toggle authored with default_off, and an effect_over_time in "activation": "active", which would otherwise start off. The one exception is a player under the Suppression effect, which switches toggles off on purpose, so the reset waits for a login without it.

Icon slots are labeled with the bound key’s short name in the top-right corner; hovering an icon while a screen is open (chat, the HUD editor) shows the power’s name and description. The hud_ability_display client config picks what the cluster shows besides live cooldowns: COOLDOWNS_AND_TOGGLES (default since 2.2.9: cooldown slots only while recharging, plus icon-bearing toggles) or ALL_ACTIVE_ABILITIES (every icon-bearing keybind ability keeps a persistent slot, full-bright while idle, sweep while recharging).

resource_cost is not a shared field. Only active_ability (plus the retired types that load as it: active_launch, active_aoe_effect, healing_mist, repulse), effect_over_time and tame_mob read resource_cost / resource_cost_amount. Every other type, including active_teleport, active_phase, active_place_block, ground_slam, tidal_wave, shadow_orb and summon_minion, ignores both keys silently: the power loads and costs nothing from the resource.

The cooldown cluster itself is draggable in the in-game HUD editor (same screen as resource bars); its position persists in config/neoorigins/hud.json.

The client-side switches mentioned above (show_cooldown_countdown, cooldown_countdown_opacity, hud_ability_display, always_show_ability_icons) live in config/neoorigins/client.toml. See CLIENT_CONFIG.md for the full list of per-client options.

neoorigins:simple

Does nothing. A display-only marker power, the direct equivalent of origins:simple from the original Origins mod.

It has no gameplay effect, no capabilities, and no behavior. Its only purpose is to appear as an entry in the origin info panel so you can attach a name + description (the heading + body text every power carries) without also granting an ability. Use it for flavor text, lore lines, or to describe an effect that is implemented elsewhere (a mixin, datapack, command, or another mod).

No additional fields beyond name and description.

Example:

{
  "type": "neoorigins:simple",
  "name": "Cold Blooded",
  "description": "You feel the chill of the deep more keenly than others."
}

Imported origins:simple / apace:simple (and origins:tooltip) powers translate to this type automatically when no specific id-override applies, so their text still shows in the GUI.

---

neoorigins:multiple

A container that bundles several powers into one. Every key in the JSON other than the shared display fields is treated as a sub-power — its own complete power object. At datapack load the container is flattened: each sub-power becomes a standalone power with the synthetic id <container-namespace>:<container-path>/<subkey>, and the origin’s power list is rewritten to reference those synthetic ids instead of the container.

Use it when a single conceptual ability is really several powers working together (a passive attribute + an on-hit action + a keybind active), so the origin panel can collapse them under one name and description instead of listing each piece.

Field	Type	Description
name / description	display fields	Shown once for the whole bundle. The origin selection screen collapses the sub-powers back under this single heading.
<subkey>	power object	Any other key is a sub-power. Its value is a full power object (any type, including a nested neoorigins:multiple). The key name becomes the last path segment of the sub-power’s synthetic id.

Sub-powers may be native neoorigins: powers or imported origins:/apoli: powers; each is loaded by the same pipeline it would use on its own. A sub-power can reference a sibling with the *:*<subkey> self-reference shorthand, which resolves to the sibling’s synthetic id.

Example: a passive flag wired to an on-hit action under one entry

{
  "type": "neoorigins:multiple",
  "name": "Venomous",
  "description": "Your strikes carry poison.",
  "poison_on_hit": {
    "type": "neoorigins:action_on_hit",
    "hidden": true,
    "entity_action": { "type": "neoorigins:apply_effect", "effect": "minecraft:poison", "duration": 60 }
  },
  "immune": {
    "type": "neoorigins:effect_immunity",
    "hidden": true,
    "effects": ["minecraft:poison"]
  }
}

This loads as two powers, <ns>:<path>/poison_on_hit and <ns>:<path>/immune, collapsed under the single “Venomous” entry.

The imported origins:multiple / apace:multiple (and apoli:multiple) containers flatten through the exact same path, so existing Apoli packs keep working unchanged. neoorigins:multiple is the first-class, in-namespace spelling for new native packs.

---

neoorigins:attribute_modifier

Adds or multiplies a player attribute while the origin is active. Optionally gated on an environment condition, an equipped-item condition, or both (AND).

Field	Type	Required	Default	Description
attribute	Identifier	yes	—	Attribute to modify, e.g. minecraft:generic.movement_speed
amount	double	yes	—	Amount to add or multiply
operation	string	no	add_value	add_value, add_multiplied_base, or add_multiplied_total (exact lowercase). Any other string, including Apoli’s addition / multiply_base, is treated as add_value without a warning.
condition	string or EntityCondition	no	—	Environment gate: in_water, on_land, or in_lava, or any entity condition object. Tick-driven apply/remove. An unknown string logs a warning and the modifier stays on unconditionally. See the note below on what on_land counts.
equipment_condition	object	no	—	Equipment gate (see below). Tick-driven apply/remove.
location_condition	object	no	—	Location gate: dimension / biome / structure (see below). Tick-driven apply/remove.

Operations:

• add_value: flat addition to base value
• add_multiplied_base: adds base * amount (e.g. -0.1 = 10% slower)
• add_multiplied_total: multiplies total after all other modifiers

equipment_condition object:

Field	Type	Required	Description
slot	string	no	One of mainhand, offhand, head, chest, legs, feet, body. Defaults to mainhand.
item	Identifier	no	Exact item ID to match (e.g. minecraft:iron_helmet)
tag	Identifier	no	Item tag to match (e.g. minecraft:helmets)

If both item and tag are given, either match satisfies the condition (OR). If neither is given, any non-empty stack in the slot counts as a match. When multiple of condition / equipment_condition / location_condition are set, all must hold for the modifier to apply.

location_condition object:

Field	Type	Required	Description
dimension	Identifier	no	Match only in this dimension, e.g. minecraft:the_end
biome	Identifier	no	Match only in this specific biome, e.g. minecraft:plains
biome_tag	Identifier	no	Match only in biomes with this tag, e.g. minecraft:is_forest
biomes	list of Identifier	no	Match only in any of these biomes
structure	Identifier	no	Match only inside this structure, e.g. minecraft:end_city
structure_tag	Identifier	no	Match only inside structures with this tag, e.g. minecraft:on_ocean_monument_maps

All fields are optional. dimension, structure and structure_tag combine with AND; the biome fields (biome, biome_tag, biomes) are OR’d with each other, so any one biome match satisfies the biome part. So { "dimension": "minecraft:the_end", "structure": "minecraft:end_city" } is “only when standing inside an End City in The End.” Structure membership is evaluated server-side via ServerLevel.structureManager().

Stacking across layers. Each attribute_modifier power owns its own modifier id, so two powers touching the same attribute add up rather than replacing one another: an origin granting +6 max health and a class granting +4 leave the player at +10. Changing one layer re-grants only that layer and leaves every other layer’s modifiers in place, so re-picking a class no longer costs the player their origin’s health, armor or reach. Modifiers left behind by a power that no longer exists (JSON deleted or renamed) are swept at that same moment, so stale bonuses cannot accumulate either.

Example: 8 flat armor (unconditional)

{
  "type": "neoorigins:attribute_modifier",
  "attribute": "minecraft:generic.armor",
  "amount": 8.0,
  "operation": "add_value",
  "name": "Shell",
  "description": "Has permanent natural armor."
}

Example: slower on land only

{
  "type": "neoorigins:attribute_modifier",
  "attribute": "minecraft:generic.movement_speed",
  "amount": -0.25,
  "operation": "add_multiplied_base",
  "condition": "on_land",
  "name": "Landwalker",
  "description": "Moves slower while out of water."
}

on_land treats an active conduit as still being in water. A player carrying Conduit Power does not count as on land, so a land penalty written this way lifts while they are in a conduit’s range instead of punishing them inside their own base. in_water is the literal check and is unaffected, which means the two are not exact opposites: a player with Conduit Power on dry ground satisfies neither. Rain is not water for either gate — a player out in a storm is on land.

Example: +1 attack when wearing any helmet

{
  "type": "neoorigins:attribute_modifier",
  "attribute": "minecraft:generic.attack_damage",
  "amount": 1.0,
  "equipment_condition": {
    "slot": "head",
    "tag": "minecraft:helmets"
  },
  "name": "Helm of Valor",
  "description": "Empowered while helmeted."
}

Example: +2 armor only inside End Cities

{
  "type": "neoorigins:attribute_modifier",
  "attribute": "minecraft:generic.armor",
  "amount": 2.0,
  "location_condition": {
    "dimension": "minecraft:the_end",
    "structure": "minecraft:end_city"
  },
  "name": "Void Ward",
  "description": "Armored while within the towers of the End."
}

Useful attributes:

• minecraft:movement_speed: walk speed (base ≈ 0.1)
• minecraft:water_movement_efficiency: swim speed boost (0.0–1.0, stacks with Depth Strider)
• minecraft:armor: armor points
• minecraft:armor_toughness: armor toughness
• minecraft:attack_damage: melee damage
• minecraft:attack_speed: attack cooldown speed
• minecraft:max_health: max HP
• minecraft:fall_damage_multiplier: fall damage scale
• minecraft:mining_efficiency: mining speed bonus
• minecraft:oxygen_bonus: extends underwater air (like Respiration)

Note: 1.21+ uses short-form IDs (minecraft:movement_speed). The legacy minecraft:generic.movement_speed format still parses via fallback.

Iron’s Spells ‘n Spellbooks attributes:

The attribute field resolves any registered attribute id, so it can target the custom attributes added by Iron’s Spells ‘n Spellbooks (irons_spellbooks). The eight ids a pack can modify:

Attribute id	add_value does	Scale
irons_spellbooks:max_mana	Flat add to mana capacity	Flat points (100.0 = +100 max mana)
irons_spellbooks:mana_regen	Mana regen multiplier	Base 1.0: 0.5 ≈ +50% regen
irons_spellbooks:spell_power	Overall spell power multiplier	Base 1.0: 0.25 ≈ +25%
irons_spellbooks:spell_resist	Incoming magic resistance	Base 1.0: 0.2 ≈ +20% resist
irons_spellbooks:cooldown_reduction	Spell cooldown reduction	Fraction 0–1 (0.15 = 15%)
irons_spellbooks:cast_time_reduction	Cast-time reduction	Fraction 0–1 (0.15 = 15%)
irons_spellbooks:casting_movespeed	Movement speed while casting	Movement-speed units
irons_spellbooks:summon_damage	Summoned-mob damage	Damage units

The operation and scale differ per attribute: max_mana is a flat add; spell_power / mana_regen / spell_resist sit on a base of 1.0, so add_value is a fractional bonus; cooldown_reduction / cast_time_reduction are 0-based fractions in 0–1. Match Iron’s own scaling. There are no per-school spell-power attributes in 3.14.0; those eight are the complete list. Referencing one on a server without Iron’s installed logs one warning per grant and applies nothing (the power still loads); gate the origin with "required_mods": ["irons_spellbooks"] if it should only exist when Iron’s is present.

neoorigins:status_effect

Deprecated in 2.0: this type is now an alias for neoorigins:persistent_effect. See MIGRATION.md.

Continuously applies a potion effect while the origin is active. The effect is refreshed every tick and removed when the origin is revoked.

Field	Type	Required	Default	Description
effect	Identifier	no	—	Effect ID, e.g. minecraft:strength. Not schema-required, but supply this or effects: with neither, the power applies nothing
amplifier	int	no	0	Effect level (0 = level I, 1 = level II, …) for the root-level effect. Alongside effects it does not cascade — it overrides the FIRST entry’s amplifier, winning even over one that entry sets itself, and leaves later entries alone
ambient	bool	no	true	Whether the effect is ambient (reduced particle visibility). Cascades onto effects entries that omit it
show_particles	bool	no	false	Whether to show particles. Cascades onto effects entries that omit it
show_icon	bool	no	true	When false the effect’s HUD status icon is hidden. Cascades onto effects entries that omit it
effects	list of EffectSpec	no	—	Multi-effect form, same per-entry shape as persistent_effect’s EffectSpec. Only ambient/show_particles/show_icon cascade from the root onto entries that omit their own: the root effect is read solely when effects is absent, and the root amplifier overrides just the first entry (see its row above)
toggleable	bool	no	true	When true the power binds a keybind that flips the effects on/off; off clears them
default_off	bool	no	false	Toggleable only: when true the effects START disabled so the player must opt in via the keybind

Example: permanent Strength I

{
  "type": "neoorigins:status_effect",
  "effect": "minecraft:strength",
  "amplifier": 0,
  "name": "Brute Strength",
  "description": "Permanently empowered by inner fire."
}

Common effects: minecraft:strength, minecraft:speed, minecraft:haste, minecraft:regeneration, minecraft:resistance, minecraft:fire_resistance, minecraft:water_breathing, minecraft:night_vision, minecraft:jump_boost, minecraft:slow_falling

---

neoorigins:stacking_status_effects

Deprecated in 2.0: this type is now an alias for neoorigins:persistent_effect. See MIGRATION.md.

Continuously applies a list of potion effects while the origin is active. Unlike status_effect (single effect) this carries a full effects array, and unlike persistent_effect it is always-on: the alias forces toggleable off, so the effects cannot be keybind-toggled.

Field	Type	Required	Default	Description
effects	list of EffectSpec	no	[]	Mob effects to apply, passed through verbatim. Same per-entry shape as persistent_effect’s EffectSpec (effect/id, amplifier, ambient, show_particles, show_icon). Not schema-required, but an empty list applies nothing.
amplifier	int	no	—	Root-level override for the first entry’s amplifier, inherited from persistent_effect. Lets power_overrides retune strength without editing the array; later entries are unchanged.

Example:

{
  "type": "neoorigins:stacking_status_effects",
  "effects": [
    { "effect": "minecraft:strength", "amplifier": 0 },
    { "effect": "minecraft:speed",    "amplifier": 1 }
  ],
  "name": "Battle Trance",
  "description": "Permanently empowered."
}

---

neoorigins:prevent_action

Prevents a specific harmful action or event from affecting the player.

Field	Type	Required	Default	Description
action	string	yes	—	The action to prevent (see values below)
active_when	string	no	"always"	Stance gate for the prevention: "always", "sneaking", "not_sneaking", "on_ground", or "not_on_ground". The action is only prevented while the condition holds.
head / chest / legs / feet	bool	no	false	Per-slot toggles for armor_equip only. When true, the matching armor slot rejects equip attempts (item snaps back to inventory, drops on the ground if full).

Action values:

Value	What it prevents
fire	All fire and lava damage
fall_damage	All fall damage
drown	Drowning damage
freeze	Freeze damage from powder snow
sprint_food	While sprinting, all hunger exhaustion is zeroed (not just the sprint cost)
armor_equip	Prevents wearing armor in any slot whose corresponding head / chest / legs / feet boolean is true. Items are ejected back to the inventory (or dropped if full).
chestplate_equip	Legacy alias of armor_equip with chest: true. Kept for back-compat with packs that pre-date armor_equip.
eye_damage	Accepted, but currently has no effect: nothing reads it
water_damage	Accepted, but currently has no effect: nothing reads it
swim	Prevents swimming (velocity-sinks the player in water)
sleep	Prevents sleeping (bed use returns a “no sleep” message). Clicking a vanilla bed still sets the respawn point before the sleep is refused.
elytra	Prevents elytra flight (player is stopped from gliding each tick)

Example: fire immunity

{
  "type": "neoorigins:prevent_action",
  "action": "fire",
  "name": "Fire Immunity",
  "description": "Immune to fire and lava."
}

Example: heavy-armor restriction (chest + legs only)

{
  "type": "neoorigins:prevent_action",
  "action": "armor_equip",
  "chest": true,
  "legs":  true,
  "name": "Light-Footed",
  "description": "Cannot wear chestplate or leggings."
}

---

neoorigins:modify_lava_speed

Modifies the player’s movement speed while submerged in lava. Uses the NumericModifierRegistry system consumed by LivingEntityLavaSpeedMixin.

Field	Type	Required	Default	Description
operation	string	no	"addition"	"addition", "multiply_base", or "multiply_total". The two multiply operations are identical here: the result is (base + additions) × (1 + Σ multiply values). Any other string is treated as "addition".
value	double	yes	—	Amount to add or multiply. Vanilla lava-swim factor is 0.02; an addition of 0.04 (3× vanilla) feels like swimming in water.

Example: water-swim-pace lava swimming

{
  "type": "neoorigins:modify_lava_speed",
  "operation": "addition",
  "value": 0.04,
  "name": "Molten Stride",
  "description": "Swims through lava as easily as others swim through water."
}

The modifier applies once, as written. Up to 2.2.27 it was added again on every respawn and every login, so a multiply_base of 0.5 became 2x after one death and kept growing until /reload or a restart. If you lowered a value to compensate, put it back.

---

neoorigins:modify_flight_speed

Scales creative / hover flight speed: the vanilla Abilities.flyingSpeed value (base 0.05) that the game reads while a player is flying. This is the in-mod equivalent of Pehkui’s pehkui:flight scale, so packs no longer need a Pehkui dependency to retune flight speed. It composes with any flight source (the creative_flight / flight powers, vanilla creative, or another mod’s mayfly) because it edits the shared flight-speed input rather than a specific flight mechanic.

It does not affect elytra / fall-flying gliding, which is physics-driven and never reads flyingSpeed, matching Pehkui’s flight scale.

Field	Type	Required	Default	Description
operation	string	no	"multiply_base"	"addition", "multiply_base", or "multiply_total". The two multiply operations are identical here; any other string is treated as "addition".
value	double	yes	—	Amount applied to the 0.05 base. multiply_base 1.0 doubles flight speed, -0.5 halves it, -0.25 ≈ Pehkui flight scale 0.75.

Multiple holders of this power stack the Apoli way (additions sum, then the multiplier deltas sum), exactly like modify_lava_speed.

Example: Pehkui flight scale 0.75 equivalent

{
  "type": "neoorigins:modify_flight_speed",
  "operation": "multiply_base",
  "value": -0.25,
  "name": "Measured Flight",
  "description": "Hovers at three-quarters the usual flight speed."
}

---

neoorigins:modify_damage

Multiplies damage dealt or received, optionally filtered to a specific damage type and, for direction: out, restricted to a target entity group.

Field	Type	Required	Default	Description
direction	string	no	in	in (damage received) or out (damage dealt)
multiplier	float	no	1.0	Damage multiplier (e.g. 2.0 = double, 0.5 = half)
damage_type	string	no	(all types)	Optional vanilla damage type to filter, e.g. drown, fire, fall
target_group	string	no	(any)	Outgoing only. Restrict to targets in this entity group: undead, arthropod, illager, aquatic. Resolved as the vanilla minecraft:<group> entity-type tag.
condition	condition	no	(always)	Only applies while this DSL condition passes.
set_total	float	no	—	Replaces the damage with this exact value after multiplier is applied.
max_total	float	no	—	Damage cap.
min_total	float	no	—	Damage floor.

The three total fields are the Apoli set_total / max_total / min_total stages and run in that order, after the multiplier: damage * multiplier → replace with set_total → cap at max_total → raise to min_total. max_total and min_total still clamp a value that set_total just wrote, so a set_total of 100 alongside a max_total of 10 yields 10. Omit a field to skip that stage.

Example: double incoming water damage

{
  "type": "neoorigins:modify_damage",
  "direction": "in",
  "multiplier": 2.5,
  "damage_type": "drown",
  "name": "Water Weakness",
  "description": "Takes extra damage from water."
}

Example: bonus fire damage dealt

{
  "type": "neoorigins:modify_damage",
  "direction": "out",
  "multiplier": 1.5,
  "damage_type": "fire",
  "name": "Fire Mastery",
  "description": "Deals extra fire damage."
}

Example: +50% damage to undead

{
  "type": "neoorigins:modify_damage",
  "direction": "out",
  "multiplier": 1.5,
  "target_group": "undead",
  "name": "Smite",
  "description": "Strikes the undead harder."
}

Common damage types: fire, in_fire, lava, drown, fall, freeze, magic, wither, lightning_bolt, fly_into_wall, generic

Matching: damage types are matched against both the vanilla message ID (camelCase, e.g. flyIntoWall) and the registry key path (snake_case, e.g. fly_into_wall). Either convention works. Tag-based filters like #minecraft:is_fire match all damage types in that tag.

---

neoorigins:prevent_death

Cancels the lethal blow instead of letting the player die. Faithful to Origins’ prevent_death, with first-class condition and damage-type gating.

Field	Type	Required	Default	Description
condition	object	no	(always)	Standard entity condition; the power only saves the player while it is true.
damage_types	string	no	(all)	Damage-type filter (comma-separated, #tags, msgIds, or registry keys). When set, only matching killing blows are prevented.
invert	bool	no	false	Flips damage_types into a blacklist: prevent all deaths except the listed types.
set_health	float	no	1.0	Health the player is left at after a save (minimum 1).
cooldown_ticks	int	no	0	After a save, the power is inert for N ticks. 0 = unlimited (Origins behavior).
entity_action	object	no	—	Optional action run on the player each time a death is prevented.

Example: survive lethal fire once every 30 s, then drop to 4 hearts

{
  "type": "neoorigins:prevent_death",
  "damage_types": "#minecraft:is_fire,lava",
  "set_health": 8.0,
  "cooldown_ticks": 600,
  "name": "Fireproof Soul",
  "description": "Cannot burn to death — but only so often."
}

Example: immortal except to the void, only while sneaking

{
  "type": "neoorigins:prevent_death",
  "damage_types": "fell_out_of_world",
  "invert": true,
  "condition": { "type": "neoorigins:sneaking" },
  "name": "Guarded Stance",
  "description": "Death cannot touch a braced body — the void still can."
}

Caveat (same as Origins): this only cancels the lethal event; it does not clear the damage source. For recurring damage-over-time (fire, lava, poison) pair it with a condition or an entity_action that removes the source, otherwise the player is re-killed on the next damage tick.

neoorigins:flight

Elytra-style fall-flight launched from a mid-air jump, as a toggle. While the toggle is on, jumping again in mid-air spreads the player’s wings and starts fall-flying without an equipped elytra; toggling the power off lands them. It is not creative hover: for that, see neoorigins:creative_flight below.

The launch is refused on the ground, in water, while riding, in spectator, and while already fall-flying.

Field	Type	Required	Default	Description
cooldown_icon	string	no	""	HUD icon (joins the ability cluster); full-bright while toggled on, dimmed while off
always_show_icon	boolean	no	false	Keep the icon on the HUD even while toggled off
render_elytra	boolean or string	no	false	When an elytra is drawn on the player’s back: false / "never" (no wings), true / "flying" (only while flying), or "always" (whenever the power is active, folded when not flying). Flight works either way; this is cosmetic only.
texture_location	identifier	no	vanilla elytra	Custom texture for the drawn elytra. Only applies when render_elytra draws wings at all; the model stays the vanilla elytra.

Example:

{
  "type": "neoorigins:flight",
  "render_elytra": true,
  "cooldown_icon": "minecraft:elytra",
  "name": "Natural Flight",
  "description": "Jump again in mid-air to take to the sky, no elytra required."
}

As with neoorigins:natural_glide, the flight runs with an empty chest slot, so nothing is drawn on the player’s back unless render_elytra is set. See the note under natural_glide for why that defaults off, and for the three values it accepts.

---

neoorigins:creative_flight

True creative-style hover flight, as a toggle. Unlike neoorigins:flight and natural_glide, which are both elytra/fall-flying mechanics, this grants real mayfly hover: the player keeps solid block collision, normal visibility and gravity when not flying. Double-tap jump to take off, then jump to rise and sneak to descend, exactly like creative mode. Intended for “ride the sword” / levitating-cultivator fantasies.

While the power is on and its condition holds, mayfly is re-asserted every tick and pushed to the client whenever it had been cleared. When the power is removed or toggled off, survival defaults are restored, but never for a creative or spectator player, so toggling off can’t lock them out of their own game mode.

Beyond name and description:

Field	Type	Required	Default	Description
condition	condition	no	always true	EntityCondition gating the flight, re-tested every tick
cooldown_icon	string	no	""	HUD icon resource path (joins the ability-icon cluster)
always_show_icon	bool	no	false	Keep the icon on the HUD even while toggled off

Requiring something of the flier. With a condition, the flight is granted only while the condition passes, and — because it is re-tested every tick — a player who breaks it in mid-air has the ability stripped and falls. That drop is the point: it turns the condition into a real cost rather than a check made once at takeoff. Toggling on while the condition fails leaves the power armed but grounded; the flight begins the moment the condition is met. The built-in Sword Immortal uses this to bind flight to the blade in hand:

{
  "type": "neoorigins:creative_flight",
  "condition": {
    "type": "neoorigins:equipped_item",
    "equipment_slot": "mainhand",
    "item_condition": { "tag": "minecraft:swords" }
  }
}

Pair a conditional flight with a fall-damage immunity (see neoorigins:prevent_action) if the drop should be survivable.

Disabling it server-side. creative_flight honors a top-level enabled flag (default true) that server owners can flip off in config/neoorigins/power_overrides.toml, keyed by the power id. When enabled = false the flight is stripped every tick and never re-granted; the origin keeps all its other powers. This is the intended way to ground a flying origin without editing datapacks; for example, the built-in Sword Immortal and Windwalker flights are:

[power_overrides.jianxian_riding_sword]
    enabled = false   # ground the Sword Immortal
[power_overrides.windwalker_riding_wind]
    enabled = false   # ground the Windwalker

Example:

{
  "type": "neoorigins:creative_flight",
  "name": "Riding the Wind",
  "description": "Double-tap jump to take to the air and fly freely."
}

neoorigins:night_vision

Deprecated in 2.0: this type is now an alias for neoorigins:persistent_effect. See MIGRATION.md.

Grants Night Vision at full strength (no ambient effect, no particles). The effect is refreshed every tick.

No additional fields beyond name and description.

Player toggle

Night vision is on by default and can be switched off by the player with the dedicated Toggle Night Vision keybind (default K), listed under NeoOrigins in the vanilla Controls menu.

• It is not an ability slot. The key is entirely separate from Skill 1–6 and from active_ability’s key pinning, so night vision costs no slot and cannot be switched off by a stray skill keypress.
• The switch is per player, not per power. One press covers every minecraft:night_vision a player is receiving, so an origin with base, evolved and ascended night-vision powers still takes exactly one press. Powers that bundle night vision with other effects (the Conduit Power line: water breathing
  • night vision + haste) lose only the night vision; the rest keeps working.
• The state is stored on the player and survives relog and death. An origin reset does not clear it.
• The server owns the flag; the client only sends “flip it” and is told the result. The disable_night_vision server config in CONTENT_CONFIG.md overrides it. Where an admin has turned night vision off globally, the key cannot turn it back on.
• Pack authors need do nothing to opt in: any power applying minecraft:night_vision through persistent_effect (including via this alias) is covered automatically. There is no per-power opt-out field.

Example:

{
  "type": "neoorigins:night_vision",
  "name": "Dark Vision",
  "description": "Can see clearly in total darkness."
}

---

neoorigins:water_breathing

Grants permanent Water Breathing. The player never loses air while underwater.

Field	Type	Required	Default	Description
enabled	bool	no	true	Kill switch: when false the power stays attached but the player breathes normally. Usually flipped from power_overrides.toml rather than the datapack.

Example:

{
  "type": "neoorigins:water_breathing",
  "name": "Gills",
  "description": "Can breathe underwater indefinitely."
}

---

neoorigins:no_slowdown

Prevents the player from being slowed by movement-impeding blocks: cobwebs, sweet berry bushes, and powder snow (the stuck-velocity clamp), plus soul sand and honey blocks (the reduced walk-speed factor).

Field	Type	Required	Default	Description
block_tag	string	no	(all slowdown blocks)	Restrict immunity to blocks in this tag. Write the tag id without #; a #-prefixed value matches nothing.

With block_tag omitted the immunity is unconditional and predicted client-side, so there’s no rubberbanding when entering a web. Restricting it to a tag keeps the check server-authoritative: a brief correction may be visible.

Example: immune to all block slowdown

{
  "type": "neoorigins:no_slowdown",
  "name": "Unimpeded",
  "description": "Not slowed by webs, soul sand, or dense foliage."
}

---

neoorigins:wall_climbing

Allows the player to cling to and climb any solid wall surface, similar to spiders. Fall damage is suppressed while climbing.

No additional fields beyond name and description.

Example:

{
  "type": "neoorigins:wall_climbing",
  "name": "Wall Climbing",
  "description": "Can scale any solid surface."
}

---

neoorigins:elytra_boost

Active (keybind) power: while the player is already gliding, pressing the key gives a firework-like boost in the look direction. It never starts a glide; pair it with natural_glide, elytra_flight or a real elytra.

Field	Type	Required	Default	Description
strength	double	no	1.5	Multiplier on the forward impulse applied while elytra gliding.
cooldown_ticks	int	no	40	Ticks before the boost can be triggered again.

Also accepts the three shared cooldown HUD fields (cooldown_icon, cooldown_countdown, always_show_icon) described at the top of this file.

Example:

{
  "type": "neoorigins:elytra_boost",
  "name": "Elytra Boost",
  "description": "Surge forward mid-glide."
}

---

neoorigins:scare_entities

Causes listed entity types to flee from the player. Every 5 ticks, matching mobs within a fixed 8-block box flee; no line of sight is needed. Matching mobs also cannot target the player unless the player hits them first. With entity_types empty nothing is scared.

Field	Type	Required	Default	Description
entity_types	list of Identifier	no	[]	Entity types to scare, e.g. ["minecraft:creeper"]
entity_blacklist	string[]	no	[]	Entity ids ("minecraft:elder_guardian") and tag refs ("#mymod:fearless") this power never scares, even when they match entity_types. Checked on top of the built-in exclusions below.

Boss-tier mobs (the Warden, Ender Dragon and Wither) are never scared, regardless of entity_types. Server operators can extend that exclusion to arbitrary mobs across all taming and scare powers at once via the tame_scare_entity_blacklist config list (see Global taming/scare exclusions). Excluded entities are simply skipped; no message is shown.

Example: creepers flee from the player

{
  "type": "neoorigins:scare_entities",
  "entity_types": ["minecraft:creeper", "minecraft:spider"],
  "name": "Predator Aura",
  "description": "Hostile arthropods flee on sight."
}

---

neoorigins:tick_action

Legacy no-op: it dispatches nothing. The type still loads and its fields still parse, so an existing pack keeps booting, but no action ever runs on the interval. Use neoorigins:condition_passive instead: it takes the same interval field and actually runs an entity_action, with an optional condition gating each run.

Field	Type	Required	Default	Description
interval	int	no	20	Parsed and ignored: nothing is dispatched on the interval.
action_type	string	no	none	Parsed and ignored. teleport_on_damage is accepted by the codec but has no behaviour behind it.

Replacement: the same shape on condition_passive

{
  "type": "neoorigins:condition_passive",
  "interval": 40,
  "entity_action": {
    "type": "neoorigins:heal",
    "amount": 1.0
  },
  "name": "Slow Mend",
  "description": "Knits itself back together every two seconds."
}

---

neoorigins:conditional

Currently only one combination does anything: condition: "climbing" with an inner_power whose path contains no_fall cancels fall damage while the player is on a climbable block. The inner power itself is not gated: it runs unconditionally, and every other condition/inner-power combination has no effect. The inner power must be a separately defined power that is also listed in the origin’s power list.

Field	Type	Required	Default	Description
condition	string	no	always	climbing, in_water, on_ground, or always
inner_power	Identifier	yes	—	The power to conditionally enable

Example: no fall damage only while climbing

{
  "type": "neoorigins:conditional",
  "condition": "climbing",
  "inner_power": "examplepack:specter_no_fall_base",
  "name": "Spider's Grip",
  "description": "Takes no fall damage while clinging to walls."
}

The inner_power must also be listed in the origin’s powers array for it to be registered.

---

neoorigins:phantom_form

A toggle (on by default, switched with the skill key). While on, the player can fly, passes through blocks and takes no fall damage, whatever the fields say. invisibility adds a hidden Invisibility effect; no_gravity also turns gravity off.

Field	Type	Required	Default	Description
invisibility	bool	no	true	Apply permanent Invisibility effect
no_gravity	bool	no	true	Disable gravity (player floats)

Example:

{
  "type": "neoorigins:phantom_form",
  "invisibility": true,
  "no_gravity": false,
  "name": "Phantom Form",
  "description": "Drift through walls unseen."
}

---

neoorigins:invisibility

Makes the player invisible. Unlike a plain invisibility status effect, this power can also hide worn armor for true invisibility (vanilla leaves armor visible on an invisible body). The invisibility rides the vanilla invisibility effect, so it is gated by the power’s top-level condition: it applies only while the condition holds and lapses when it stops.

Field	Type	Required	Default	Description
render_armor	bool	no	true	When true, worn armor stays visible (vanilla behaviour). When false, worn armor and held items are also hidden client-side for true invisibility. That hiding applies whenever the player is invisible from any source, even while this power’s condition is false.

Example:

{
  "type": "neoorigins:invisibility",
  "render_armor": false,
  "name": "Vanish",
  "description": "Become completely invisible, armor and all."
}

This is the native type the Apoli compat layer maps origins:invisibility (and apace:invisibility) onto, carrying the render_armor field through.

---

neoorigins:prevent_entity_render

Hides other entities from the holder. Every living entity matching entity_condition stops being drawn for this player only — everyone else still sees it normally, and the entity is otherwise untouched: it still moves, still attacks, and still collides. Only living entities are candidates, so boats, minecarts, item frames, dropped items and projectiles are never hidden. Pair it with a power that applies glowing to build a “you only see what you have revealed” origin.

The condition is evaluated on the server, which then tells the client which entities to skip. That is what lets verbs like status_effect and nbt work here, since a client never receives another entity’s effects or full NBT.

Field	Type	Required	Default	Description
entity_condition	condition	no	—	Tested against each nearby living entity; every one that passes becomes invisible to the holder. Omit it to hide every living entity. Because the subject is an arbitrary entity rather than the holder, only entity-general verbs apply: entity_type, in_tag, target_group, living, on_fire, health, relative_health, status_effect / has_effect, nbt, constant, and and / or / not over those. A condition using anything else is not refused — the power loads, warns, and hides nothing rather than hiding everything. Takes one condition object, or an array of them, which is read as all of them AND-combined.

Refresh rate and scope. The hidden set is recomputed every 5 ticks, over the living entities within the server’s view distance and no further than 256 blocks. An entity that starts or stops matching therefore appears or disappears up to a quarter of a second later. At most 1024 entities are hidden from one player at a time; past that, the remainder stay visible.

Example: only glowing creatures are visible

{
  "type": "neoorigins:prevent_entity_render",
  "entity_condition": {
    "type": "neoorigins:and",
    "conditions": [
      { "type": "neoorigins:living" },
      { "type": "neoorigins:status_effect", "effect": "minecraft:glowing", "inverted": true }
    ]
  },
  "name": "Blind Sight",
  "description": "You see nothing but what you have marked."
}

This is the native type the Apoli compat layer maps origins:prevent_entity_render (and apace:prevent_entity_render) onto, carrying entity_condition through. Apoli’s bientity_condition variant is not translated, because half of the pair it compares is the observer.

---

neoorigins:effect_immunity

Prevents listed potion effects from being applied to the player. Uses NeoForge’s MobEffectEvent.Applicable to cancel before application.

Field	Type	Required	Default	Description
effects	list of string	no	[]	Effect IDs to block, e.g. ["minecraft:poison"]. Supply it unless inverted is true: an empty list on its own grants no immunity at all
inverted	bool	no	false	Flips the list into an exception list (Apoli semantics): immune to every effect except those listed. true with an empty list = immune to all effects.

Example:

{
  "type": "neoorigins:effect_immunity",
  "effects": ["minecraft:poison", "minecraft:wither"],
  "name": "Toxin Resistance",
  "description": "Immune to poison and wither effects."
}

Example: immune to everything except regeneration

{
  "type": "neoorigins:effect_immunity",
  "effects": ["minecraft:regeneration"],
  "inverted": true
}

Pair inverted: true with an empty effects list and a power_condition for a temporary blanket immunity (e.g. an immunity-shot buff gated on a resource).

---

neoorigins:glow

Deprecated in 2.0: this type is now an alias for neoorigins:persistent_effect. See MIGRATION.md.

Applies a permanent Glowing effect to the player (visible outline through walls for other players).

No additional fields beyond name and description.

Example:

{
  "type": "neoorigins:glow",
  "name": "Bioluminescence",
  "description": "Emits a faint glow visible to others."
}

---

neoorigins:damage_in_daylight

Deprecated in 2.0: this type is now an alias for neoorigins:condition_passive. See MIGRATION.md.

Deals periodic damage to the player when they are in direct sunlight (sky-exposed, not in shade or water). Fires once per second (the interval is fixed at 20 ticks). Damage and ignition can be combined; set damage_per_second to 0 for an ignite-only effect.

Field	Type	Required	Default	Description
damage_per_second	float	no	1.0	Damage applied each second (set 0 to disable)
ignite	bool	no	false	Also set the player on fire each second
fire_ticks	int	no	40	Burn duration in ticks when ignite is true

Example:

{
  "type": "neoorigins:damage_in_daylight",
  "damage_per_second": 1.0,
  "name": "Sun Allergy",
  "description": "Burns in direct sunlight."
}

---

neoorigins:damage_in_water

Deprecated in 2.0: this type is now an alias for neoorigins:condition_passive. See MIGRATION.md.

Deals periodic drown damage to the player while they are in water, and, when include_rain is enabled, while they are exposed to rain. Damage is applied once per second.

Field	Type	Required	Default	Description
damage_per_second	float	no	1.0	Damage dealt each second (half-hearts). Set to 0 to disable damage entirely: the power still loads but substitutes a no-op so no hurt sound/animation fires.
multiplier	float	no	1.0	Scale factor applied on top of damage_per_second — the effective rate is damage_per_second × multiplier. Not a synonym: writing both applies both. Setting either to 0 disables the power.
include_rain	bool	no	true	When true, damage also applies while exposed to rain (in_water OR in_rain); when false, only while in water.

Example:

{
  "type": "neoorigins:damage_in_water",
  "damage_per_second": 2.0,
  "include_rain": true,
  "name": "Hydrophobia",
  "description": "Burns when touched by water or rain."
}

---

neoorigins:knockback_modifier

Deprecated in 2.0: this type is now an alias for neoorigins:action_on_event. See MIGRATION.md.

Multiplies the knockback the player receives. There is no outgoing form: the alias always emits event: mod_knockback, which fires on the knockback applied to the player.

Field	Type	Required	Default	Description
multiplier	float	no	1.0	Knockback multiplier. 0 or less cancels the knockback outright.

Example: halve knockback taken

{
  "type": "neoorigins:knockback_modifier",
  "multiplier": 0.5,
  "name": "Sturdy",
  "description": "Resistant to knockback."
}

---

neoorigins:longer_potions

Deprecated in 2.0: this type is now an alias for neoorigins:action_on_event. See MIGRATION.md.

Multiplies the duration of potion effects applied to the player (mod_potion_duration event).

Field	Type	Required	Default	Description
duration_multiplier	float	no	1.0	Multiplier applied to potion effect duration

Example: potions last twice as long

{
  "type": "neoorigins:longer_potions",
  "duration_multiplier": 2.0,
  "name": "Slow Metabolism",
  "description": "Potions linger far longer."
}

---

neoorigins:more_animal_loot

Deprecated in 2.0: this type is now an alias for neoorigins:action_on_event. See MIGRATION.md.

Multiplies the number of drops harvested from killed animals/mobs (mod_harvest_drops event).

Field	Type	Required	Default	Description
multiplier	float	no	1.0	Multiplier applied to harvest drop count

Example:

{
  "type": "neoorigins:more_animal_loot",
  "multiplier": 2.0,
  "name": "Hunter's Bounty",
  "description": "Animals yield double drops."
}

---

neoorigins:efficient_repairs

Deprecated in 2.0: this type is now an alias for neoorigins:action_on_event. See MIGRATION.md.

Multiplies the experience-level cost of anvil repairs (mod_anvil_cost event). Use a value below 1.0 to make repairs cheaper.

Field	Type	Required	Default	Description
cost_multiplier	float	no	1.0	Multiplier applied to the anvil level cost

Example: half-price anvil repairs

{
  "type": "neoorigins:efficient_repairs",
  "cost_multiplier": 0.5,
  "name": "Master Smith",
  "description": "Anvil repairs cost half the levels."
}

---

neoorigins:better_enchanting

Deprecated in 2.0: this type is now an alias for neoorigins:action_on_event. See MIGRATION.md.

Adds a flat bonus to the enchantment power level available at the enchanting table (mod_enchant_level event). The bonus is additive (add_base), not a multiplier.

Field	Type	Required	Default	Description
bonus_levels	int	no	5	Bonus enchanting levels added

Example:

{
  "type": "neoorigins:better_enchanting",
  "bonus_levels": 5,
  "name": "Arcane Affinity",
  "description": "Enchants as though surrounded by extra bookshelves."
}

---

neoorigins:better_crafted_food

Deprecated in 2.0: this type is now an alias for neoorigins:action_on_event. See MIGRATION.md.

Adds a flat saturation bonus to food the player crafts (mod_crafted_food_saturation event). Additive (add_base).

Field	Type	Required	Default	Description
saturation_bonus	float	no	0.5	Extra saturation added to crafted food

Example:

{
  "type": "neoorigins:better_crafted_food",
  "saturation_bonus": 1.0,
  "name": "Home Cooking",
  "description": "Food you make is more filling."
}

---

neoorigins:better_bone_meal

Deprecated in 2.0: this type is now an alias for neoorigins:action_on_event. See MIGRATION.md.

Grants extra bone-meal growth applications per use (mod_bonemeal_extra event). Additive (add_base).

Field	Type	Required	Default	Description
extra_applications	int	no	1	Additional bone-meal growth applications per use

Example:

{
  "type": "neoorigins:better_bone_meal",
  "extra_applications": 2,
  "name": "Green Thumb",
  "description": "Bone meal goes further."
}

---

neoorigins:teleport_range_modifier

Deprecated in 2.0: this type is now an alias for neoorigins:action_on_event. See MIGRATION.md.

Multiplies the player’s teleport range (e.g. ender-pearl throw distance) via the mod_teleport_range event.

Field	Type	Required	Default	Description
multiplier	float	no	2.0	Multiplier applied to teleport range

Example:

{
  "type": "neoorigins:teleport_range_modifier",
  "multiplier": 2.0,
  "name": "Far Step",
  "description": "Teleports reach twice as far."
}

---

origins:modify_xp_gain

Multiplies experience points gained. Wired to PlayerXpEvent.XpChange via the NumericModifierRegistry. Uses Apoli modifier math (addition / multiply_base / multiply_total).

Use origins:modify_xp_gain, not neoorigins:xp_gain_modifier. There is no native neoorigins: XP-gain type; the only working implementation is this Apoli compat (Route B) verb. A power whose type is unregistered is dropped entirely at load (its name and description vanish from the picker too), so the neoorigins:xp_gain_modifier name in older docs never worked.

Takes an Apoli modifier (singular modifier object or plural modifiers array). Each entry is { "operation": ..., "value": ... } (value may also be written amount).

Field	Type	Required	Default	Description
modifier / modifiers	object / array	no	—	Apoli modifier(s): operation (addition, multiply_base, multiply_total; the two multiply operations are identical, and any other string is treated as addition) + value. Not schema-required, but supply one: with neither key the loader logs missing modifier/modifiers and drops the power entirely. There is no condition gate on this type

Example: gain 50% more XP

{
  "type": "origins:modify_xp_gain",
  "modifier": { "operation": "multiply_base", "value": 0.5 },
  "name": "Quick Learner",
  "description": "Gains experience faster."
}

The modifier applies once, as written. Up to 2.2.27 it was added again on every respawn and every login, so the +50% above became +100% after one death and kept growing until /reload or a restart. If you lowered a value to compensate, put it back.

---

origins:modify_fall_damage

Scales incoming fall damage, optionally gated by a condition. This is an Apoli compat (Route B) verb; there is no native neoorigins: fall-damage type. It reuses the existing native fall-damage seam: the loader registers a mod_fall_damage modifier handler (the same hook neoorigins:action_on_event with event: mod_fall_damage uses), which chains onto the LivingFallEvent damage multiplier in MovementPowerEvents.onLivingFall. Because it chains, it stacks with feather-falling and other fall-damage modifiers.

Takes an Apoli modifier (singular modifier object or plural modifiers array). Each entry is { "operation": ..., "value": ... } (value may also be written amount). The operation+value is applied through the same modifier math as the other compat verbs: multiply_base_additive with value: -0.5 → damage * (1 + -0.5) (halved); addition/add_base adds a flat amount to the multiplier; set_total with value: 0 hard-zeroes the multiplier (no fall damage). A condition that targets fall_damage written as a conditioned_attribute is auto-routed here (vanilla has no fall-damage attribute, so it would otherwise be dropped).

Field	Type	Required	Default	Description
modifier / modifiers	object / array	no	—	Apoli modifier(s): operation + value applied to the fall-damage multiplier. Not schema-required, but supply one: with neither key the loader logs missing modifier/modifiers and drops the power entirely
condition	object / array	no	always	Entity condition gating when the scale applies (e.g. only while sneaking)

Example: halved fall damage while sneaking

{
  "type": "origins:modify_fall_damage",
  "modifier": { "operation": "multiply_base_additive", "value": -0.5 },
  "condition": { "type": "origins:sneaking" },
  "name": "Soft Landing",
  "description": "Takes half fall damage while sneaking."
}

---

origins:modify_healing

Scales health the holder regains. This is an Apoli compat (Route B) verb; there is no native neoorigins: healing-modifier type. It reuses the existing native seam: the loader registers a mod_natural_regen modifier handler, which WorldPowerEvents.onLivingHeal chains onto LivingHealEvent. That event fires for all healing, not just natural regeneration (potions, golden apples and /heal go through it too), which matches Apoli’s contract for this type.

Takes an Apoli modifier (singular modifier object or plural modifiers array). This is a 1.16–1.18-vintage Origins type, so its packs use the attribute-style operation names: addition adds a flat amount, while multiply_base and multiply_total sum into base + base * Σvalue. A single multiply_total of 0.5 is therefore 1.5x healing, and multiply_base of -0.5 is half healing.

Field	Type	Required	Default	Description
modifier / modifiers	object / array	no	—	Apoli modifier(s): operation + value applied to the heal amount. Not schema-required, but supply one: with neither key the loader logs missing 'modifier'/'modifiers' and drops the power entirely
condition	object / array	no	always	Entity condition gating when the scale applies

Example: healing halved

{
  "type": "origins:modify_healing",
  "modifier": { "operation": "multiply_base", "value": -0.5 },
  "name": "Slower Regeneration",
  "description": "As a flower your healing capabilities are limited."
}

---

origins:modify_status_effect_duration

Scales the duration of mob effects applied to the holder. Apoli compat (Route B), the duration-side sibling of origins:modify_status_effect_amplifier. The loader registers a mod_potion_duration modifier handler, which CombatPowerEvents chains onto MobEffectEvent.Added.

The seam collects a multiplier: its base is 1.0, and the dispatch site applies the result to the effect instance’s duration. So multiply_total with value: 0.5 yields 1.5x and reads as “effects last 50% longer”. Operation names are the same attribute-style set modify_healing uses. The scale applies to every effect added to the holder; there is no per-effect filter.

Field	Type	Required	Default	Description
modifier / modifiers	object / array	no	—	Apoli modifier(s) applied to the duration multiplier. Not schema-required, but supply one: with neither key the loader logs missing 'modifier'/'modifiers' and drops the power entirely
condition	object / array	no	always	Entity condition gating when the scale applies

Example: beneficial effects last 50% longer

{
  "type": "origins:modify_status_effect_duration",
  "modifier": { "operation": "multiply_total", "value": 0.5 },
  "name": "Extended Potion Effects",
  "description": "Potion effects last longer for you."
}

origins:action_on_death

Fires when the holder dies. Apoli compat (Route B), riding the native death event seam that CombatPowerEvents.onLivingDeath already dispatches.

entity_action runs on the dying holder. bientity_action runs with actor = the holder and target = the killer, Apoli’s pairing for this type. The bientity half is skipped entirely when the death had no living attacker (fall damage, drowning, /kill) because there is no target to pair with, and running the action against the holder would invert its meaning.

Field	Type	Required	Default	Description
entity_action	object	no	—	Action run on the dying holder
bientity_action	object	no	—	Action run as (actor = holder, target = killer); skipped when there is no living killer
condition	object / array	no	always	Entity condition on the holder, tested at death time

Example: run a function as whoever killed you

{
  "type": "origins:action_on_death",
  "hidden": true,
  "bientity_action": {
    "type": "origins:target_action",
    "action": { "type": "origins:execute_command", "command": "function mypack:on_death" }
  }
}

---

apugli:action_on_jump

Fires when the holder jumps. Apugli compat: the loader remaps it onto neoorigins:action_on_event with event pinned to jump, so the whole jump seam and every action in ACTIONS.md is available. Apugli was abandoned at 2.11.0+1.20.4, so this id only appears in packs shipped against it — new packs should write action_on_event directly.

Because event is pinned, the filter fields that only mean something for other events (block_condition, hands/hand, item_condition, effect, effect_tag, power, immunity_ticks) are not offered here, and neither is modifier: the jump seam dispatches the action path only, so a modifier chain would never be consulted.

Field	Type	Required	Default	Description
entity_action	EntityAction	no	noop	Action run on the holder when they jump
condition	EntityCondition	no	always-true	Gate: the jump only fires the action while this is true
cooldown_ticks	int ≥ 0	no	0	After the action fires, suppress further firings for this many ticks (20 = 1s)

Example: cost a little hunger per jump

{
  "type": "apugli:action_on_jump",
  "entity_action": { "type": "origins:exhaust", "amount": 1.0 }
}

---

apugli:action_on_target_death

Fires when the holder lands the killing blow on another entity. Apugli compat: remapped onto neoorigins:action_on_event with event pinned to kill. Same deprecation note as action_on_jump.

The action runs on the killer, never the victim. Apugli’s bi-entity spelling has no counterpart here for that reason: the kill hook carries only the holder, so a bientity_action would be read by nothing and is deliberately not offered. Field set is identical to action_on_jump, and for the same reason.

Field	Type	Required	Default	Description
entity_action	EntityAction	no	noop	Action run on the holder when they get a kill
condition	EntityCondition	no	always-true	Gate: the kill only fires the action while this is true
cooldown_ticks	int ≥ 0	no	0	After the action fires, suppress further firings for this many ticks (20 = 1s)

Example: heal a heart per kill

{
  "type": "apugli:action_on_target_death",
  "entity_action": { "type": "origins:heal", "amount": 2.0 }
}

---

origins:cooldown

A readable cooldown timer. This is an Apoli compat (Route B) power; there is no native neoorigins: cooldown power type (native active powers carry their own cooldown_ticks). An Apoli cooldown power is a countdown resource: its value is 0 while ready and counts down from the armed duration, one per tick, while running. That makes it readable everywhere resources are: neoorigins:resource / resource_level conditions, change_resource / set_resource actions, and the HUD bar.

Arming: the neoorigins:trigger_cooldown action sets the resource to the power’s registered cooldown duration. Its power field may be the full power id, a legacy slash id, or a wildcard glob like *:*_timer; the glob is matched against the player’s resource keys at runtime and every matching cooldown power is armed. The canonical Apoli pattern (inside an origins:multiple, where the *:*_timer self-reference in a condition resolves to the sibling timer’s synthetic id at expansion): fire an ability, trigger_cooldown the timer, then gate the ability on the timer resource being 0. A running countdown persists across relogs.

Field	Type	Required	Default	Description
cooldown	int ticks	no	1	Countdown duration armed by trigger_cooldown (clamped to ≥ 1)
hidden	bool	no	false	Hide the HUD bar
hud_render	object	no	—	Same shape as the neoorigins:resource HUD block: sprite_location, bar_index / icon_index (default 0 when the block is present), should_render (false → hidden), condition (entity condition gating bar visibility)

The duration and bar settings are shared by every holder of the power, and losing the power only clears that player’s own timer. Up to 2.2.27, one player losing it also stripped the registered duration from everyone else until the next /reload or restart.

Example: a 10-second ability timer, read back as a resource

{
  "type": "origins:cooldown",
  "cooldown": 200,
  "hud_render": { "should_render": false }
}

---

neoorigins:underwater_mining_speed

Removes the normal mining speed penalty for being submerged in water. The player mines at full speed underwater.

No additional fields beyond name and description.

Example:

{
  "type": "neoorigins:underwater_mining_speed",
  "name": "Aquatic Miner",
  "description": "Mines at full speed underwater."
}

---

neoorigins:hunger_drain_modifier

Deprecated in 2.0: this type is now an alias for neoorigins:action_on_event. See MIGRATION.md.

Multiplies the rate at which the player’s hunger depletes.

Field	Type	Required	Default	Description
multiplier	float	no	1.0	Hunger drain multiplier (1.3 = 30% faster, 0.5 = half rate)

Example:

{
  "type": "neoorigins:hunger_drain_modifier",
  "multiplier": 1.3,
  "name": "High Metabolism",
  "description": "Gets hungry faster than normal."
}

---

neoorigins:natural_regen_modifier

Deprecated in 2.0: this type is now an alias for neoorigins:action_on_event. See MIGRATION.md.

Multiplies all healing the player receives via LivingHealEvent. Note: this is not limited to food-tick natural regen; it also scales Regeneration potion ticks, beacon regen, totem of undying, and any data-pack neoorigins:heal actions. If you want to cancel food-tick regen specifically while leaving other heals intact, use neoorigins:no_natural_regen instead.

Field	Type	Required	Default	Description
multiplier	float	no	1.0	Heal multiplier (0.5 = half all heals, 2.0 = double all heals, 0.0 = block all heals)

Example:

{
  "type": "neoorigins:natural_regen_modifier",
  "multiplier": 0.5,
  "name": "Slow Recovery",
  "description": "Heals at half the normal rate."
}

---

neoorigins:no_natural_regen

Cancels vanilla food-based natural regeneration only. Both regen branches (saturation-based fast regen and food-level-≥18 slow regen) are skipped. Other heal sources (Regeneration potion, beacon, totem, neoorigins:heal) still work normally. Pair with an alternate healing mechanic for “metabolism-less” origins like Automaton variants.

No fields. Presence of the power is the entire configuration.

Example:

{
  "type": "neoorigins:no_natural_regen",
  "name": "No Pulse",
  "description": "Hunger doesn't restore HP. Only direct healing effects do."
}

---

neoorigins:food_restriction

Deprecated in 2.0: this type is now an alias for neoorigins:action_on_event. See MIGRATION.md.

Restricts which foods the player can eat. Supports blacklist (cannot eat items matching the tag/item list) and whitelist (can only eat items matching). item_tag accepts a single string or a JSON array of tags and/or item IDs. Prefix entries with # for tags; bare strings match exact item IDs.

Field	Type	Required	Default	Description
mode	string	no	"blacklist"	"blacklist" or "whitelist"
item_tag	string or array	no	—	Single tag/item or array of tags/items. Use # prefix for tags (e.g. "#minecraft:meat"), bare strings for item IDs (e.g. "minecraft:spider_eye"). Not schema-required, but supply this or allowed_tags: with neither, a blacklist restricts nothing and a whitelist forbids everything.
allowed_tags	string or array	no	—	Alias for item_tag, read only when item_tag is absent. Same single-or-array shape.

Example: meat-only diet (whitelist)

{
  "type": "neoorigins:food_restriction",
  "mode": "whitelist",
  "item_tag": "#minecraft:meat",
  "name": "Carnivore",
  "description": "Can only eat meat."
}

Example: vegetarian with multiple blacklisted tags

{
  "type": "neoorigins:food_restriction",
  "mode": "blacklist",
  "item_tag": ["#minecraft:meat", "#c:foods/raw_meat"],
  "name": "Vegetarian",
  "description": "Cannot eat meat."
}

Example: blacklist specific items and a tag

{
  "type": "neoorigins:food_restriction",
  "mode": "blacklist",
  "item_tag": ["#minecraft:meat", "minecraft:spider_eye", "minecraft:rotten_flesh"],
  "name": "Clean Eater",
  "description": "Cannot eat meat or unsanitary foods."
}

---

neoorigins:item_magnetism

Items on the ground within a radius are pulled toward the player automatically. A toggle, on by default.

Field	Type	Required	Default	Description
radius	float	no	4.0	Pull radius in blocks

Example:

{
  "type": "neoorigins:item_magnetism",
  "radius": 4.0,
  "name": "Item Attraction",
  "description": "Items on the ground are drawn toward you."
}

---

neoorigins:break_speed_modifier

Multiplies the player’s mining speed when breaking blocks in the specified tag. When no tag is provided, applies to all blocks.

Field	Type	Required	Default	Description
block_tag	Identifier	no	(all blocks)	Block tag to restrict the modifier to, e.g. #minecraft:base_stone_overworld. A bare id is tried as a tag first, then as a single block; a leading # forces a tag.
multiplier	float	no	2.0	Speed multiplier (2.0 = double speed)

Example: 2× speed on stone and deepslate

{
  "type": "neoorigins:break_speed_modifier",
  "block_tag": "#minecraft:base_stone_overworld",
  "multiplier": 2.0,
  "name": "Stone Affinity",
  "description": "Mines stone and deepslate twice as fast."
}

---

neoorigins:thorns_aura

Deprecated in 2.0: this type is now an alias for neoorigins:action_on_event. See MIGRATION.md.

Reflects a portion of incoming melee damage back to the attacker.

Field	Type	Required	Default	Description
return_ratio	float	no	0.25	Fraction of damage dealt back (0.25 = 25%)

Example:

{
  "type": "neoorigins:thorns_aura",
  "return_ratio": 0.5,
  "name": "Thorny Hide",
  "description": "Reflects half of incoming melee damage."
}

---

neoorigins:projectile_immunity

Negates incoming projectile damage (arrows, tridents, fireballs, etc.). Which projectiles are blocked, and how reliably, are both configurable; the defaults block every arrow.

Field	Type	Required	Default	Description
projectile_types	list of strings	no	["arrow"]	Projectiles blocked: arrow (every arrow-type projectile, which includes thrown tridents), fireball, trident, all, or an entity id.
chance	double (0.0–1.0)	no	1.0	Probability an incoming matching projectile is negated.
teleport	bool	no	false	When true a successful dodge triggers a short random teleport.
teleport_range	int	no	16	Max teleport distance in blocks on a dodge, when teleport is enabled.

Example:

{
  "type": "neoorigins:projectile_immunity",
  "projectile_types": ["all"],
  "name": "Arrow Deflection",
  "description": "Immune to all projectile damage."
}

---

neoorigins:action_on_kill

Deprecated in 2.0: this type is now an alias for neoorigins:action_on_event. See MIGRATION.md.

Triggers an action each time the player kills a living entity.

Field	Type	Required	Default	Description
action	string	no	restore_health	Action to perform: restore_health, restore_hunger, grant_effect
amount	float	no	4.0	Health or hunger to restore
effect	Identifier	no	—	Effect to grant (when action is grant_effect)
amplifier	int	no	0	Effect level
duration	int	no	200	Effect duration in ticks

Example: restore 1 heart on kill

{
  "type": "neoorigins:action_on_kill",
  "action": "restore_health",
  "amount": 2.0,
  "name": "Vampiric",
  "description": "Restores health by killing enemies."
}

---

neoorigins:action_on_hit_taken

Deprecated in 2.0: this type is now an alias for neoorigins:action_on_event. See MIGRATION.md.

Triggers an action each time the player takes damage.

Field	Type	Required	Default	Description
action	string	no	teleport	Action to perform: teleport (random teleport, 16 blocks horizontal / 8 vertical), ignite_attacker, or effect_on_attacker. Any other value falls back to teleport.
min_damage	float	no	0.0	Only fires when incoming damage ≥ this
chance	float	no	1.0	Probability to fire, from 0.0 to 1.0
effect	Identifier	no	—	Effect to apply to the attacker. Read only by effect_on_attacker.
amplifier	int	no	0	Effect level. Read only by effect_on_attacker.
duration	int	no	100	Effect duration in ticks for effect_on_attacker, or burn time for ignite_attacker — where it defaults to 60 instead.

Example: poison whoever hits you

{
  "type": "neoorigins:action_on_hit_taken",
  "action": "effect_on_attacker",
  "effect": "minecraft:poison",
  "amplifier": 1,
  "duration": 60,
  "name": "Toxic Blood",
  "description": "Poisons attackers who draw blood."
}

This type can only act on the attacker. To buff yourself when hit, use neoorigins:action_on_event with "event": "hit_taken" and an entity_action, which runs against the player.

---

neoorigins:action_on_hit

Triggers an action each time the player deals damage to any living entity: mobs, animals, and other players. Optionally restricted by target entity group, target entity type, or damage type. There are two ways to express the effect: the simple flat action string (self or victim), or a full Apoli-style bientity_action (alias entity_action) that runs against the (attacker, victim) pair. Both may be present — the flat action runs first, then the parsed bientity action.

Field	Type	Required	Default	Description
action	string	no	restore_health (none when entity_action or bientity_action is set)	One of restore_health, restore_hunger, grant_effect (self), target_effect (victim), or none / nothing
amount	float	no	2.0	Health or hunger amount (for the restore actions)
effect	Identifier	no	—	Effect to apply for grant_effect / target_effect
duration	int	no	100	Effect duration in ticks
amplifier	int	no	0	Effect level
min_damage	float	no	0.0	Only fires when outgoing damage ≥ this
chance	float	no	1.0	Probability to fire, from 0.0 to 1.0
target_group	string	no	(any)	Restrict to targets in group: undead, arthropod, illager, aquatic (vanilla minecraft:<group> entity-type tag)
target_type	Identifier	no	(any)	Restrict to a specific entity type, e.g. minecraft:zombie
damage_type	string	no	(all)	Restrict to a specific vanilla damage type, e.g. mob_attack, magic
bientity_action	entity action (object or array)	no	noop	Parsed action run against the pair: actor = the attacker (you), target = the entity you hit. A bare verb (e.g. apply_effect) runs against the victim; wrap in actor_action / target_action to route explicitly. See ACTIONS.md: bientity actions.
entity_action	entity action (object or array)	no	noop	Alias for bientity_action: the field name a pack copying the ACTIONS.md example uses.

Filters are combined with AND: every configured filter must match for the action to fire. The chance roll happens last. The same filter gates (min_damage, damage_type, target_group, target_type, chance) govern the bientity_action too.

Example: heal 0.5 hearts on striking any undead

{
  "type": "neoorigins:action_on_hit",
  "action": "restore_health",
  "amount": 1.0,
  "target_group": "undead",
  "name": "Smite Vigor",
  "description": "Drains life from the undead with each blow."
}

Example: mark the victim with Glowing when striking undead

{
  "type": "neoorigins:action_on_hit",
  "action": "target_effect",
  "effect": "minecraft:glowing",
  "duration": 60,
  "target_group": "undead",
  "name": "Holy Mark",
  "description": "Hit undead are illuminated briefly."
}

Example: 20% chance to gain Strength I on hitting a zombie, on melee only

{
  "type": "neoorigins:action_on_hit",
  "action": "grant_effect",
  "effect": "minecraft:strength",
  "duration": 60,
  "chance": 0.2,
  "damage_type": "mob_attack",
  "target_type": "minecraft:zombie",
  "name": "Adrenal Surge",
  "description": "Sometimes empowered when you melee a zombie."
}

Example: poison whatever you hit (bientity form)

{
  "type": "neoorigins:action_on_hit",
  "hidden": true,
  "entity_action": { "type": "neoorigins:apply_effect", "effect": "minecraft:poison", "duration": 60 },
  "name": "Venom Strike",
  "description": "Your blows leave a lingering poison."
}

The bare apply_effect runs against the victim: hitting a mob poisons it. To affect yourself instead, wrap it in actor_action; to be explicit about targeting the victim, wrap it in target_action.

---

neoorigins:regen_in_fluid

Deprecated in 2.0: this type is now an alias for neoorigins:condition_passive. See MIGRATION.md.

Grants periodic health regeneration while submerged in the specified fluid. Healing fires once per second (the interval is fixed at 20 ticks).

Field	Type	Required	Default	Description
fluid	string	no	water	Fluid to trigger in: water or lava
amount_per_second	float	no	1.0	Health restored each second

Example:

{
  "type": "neoorigins:regen_in_fluid",
  "fluid": "water",
  "amount_per_second": 1.0,
  "name": "Aquatic Regeneration",
  "description": "Regenerates health while underwater."
}

---

neoorigins:breath_in_fluid

Drains the player’s air supply when their eyes are submerged in the specified fluid. Useful for fire-themed origins that “drown” in water. Surfacing (head above water) restores air normally via vanilla breathing. While submerged, fully overrides vanilla’s air management (suppresses both vanilla drowning and water-breathing refill), so the configured drain rate is the sole authority on how fast air depletes. Respiration enchantment extends survival time. Drown damage (2 HP/sec) applies once air is exhausted.

Field	Type	Required	Default	Description
fluid	string	no	water	Fluid: water or lava
air_loss_per_second	int	no	—	Intuitive form: how many air points are lost per second. Higher = faster drain. Internally converted to ticks via 20 / value.
drain_interval_ticks	int	no	—	Ticks between each air drain. Higher = slower drain. Equivalent to the legacy drain_rate.
drain_rate	int	no	20	Legacy alias for drain_interval_ticks. Resolution priority: air_loss_per_second > drain_interval_ticks > drain_rate > default 20 (one decrement per second).

Example:

{
  "type": "neoorigins:breath_in_fluid",
  "fluid": "water",
  "air_loss_per_second": 1,
  "name": "Hydrophobic",
  "description": "Cannot breathe in water."
}

---

neoorigins:breath_out_of_fluid

Drains the player’s air supply while they are not submerged in the specified fluid: a fish out of water. Once the air supply reaches 0, vanilla drown damage applies. For the water form, rain, a bubble column and standing in a water cauldron all count as being in the fluid. Water Breathing and Conduit Power effects pause the drain, and drinking a water bottle restores half the air bar. Vanilla only grants Conduit Power to a player who is already in water or rain, which would put it out of reach of the one situation this power creates; the mod lifts that restriction for players holding this power, so an active conduit reaches them anywhere in its normal radius and the air bar refills while they stand there. Compatible with Create’s Copper Backtank (worn in chestplate slot, consumes pressurized air to pause drain). Respiration enchantment extends land time using the same probability curve vanilla uses underwater. fluid: lava is the bare check: none of these reprieves reach it, only being in lava itself.

The drain rate is per-power. Set one of the three fields below and that power drains at your rate; omit all three and the power falls back to the global ocean_origins.drain_rate_ticks config, which is how the four built-in *_dries_out powers are written. If a player holds more than one of these powers, the tightest interval wins.

Field	Type	Required	Default	Description
fluid	string	no	water	Fluid the player must stay in: water or lava
air_loss_per_second	int	no	config	Highest priority: air points lost per second (higher = faster drain)
drain_interval_ticks	int	no	config	Ticks between each 1-point drain (higher = slower drain; 20 = 1s)
drain_rate	int	no	config	Legacy alias for drain_interval_ticks, lowest priority

Air starts at 300, so land time in seconds is roughly (300 × drain_interval_ticks) / 20: 1 gives 15s (vanilla cod parity), 2 gives 30s, 4 gives a minute.

Count bars, not bubbles. The interval is ticks per single air point, and the HUD draws 300 air as 10 bubbles, so one bubble is 30 points. At 1 a bubble lasts 1.5s and the whole bar 15s; at 10 a bubble lasts a full 15s and the bar 150s. Both figures have been reported as bugs by players reading the bubble as the unit, so it is worth checking which one you are timing. If your bar empties far slower than the table says, check config/neoorigins/gameplay.toml: ModConfigSpec writes that file once and never re-defaults it, so a world that was played before the default changed from 10 to 1 still holds the old value. As of 2.2.24 the mod corrects that one case itself on the first start and stamps the file with a config_version, after which the setting is yours: put it back to 10 and it stays there.

Example: aquatic origin that drowns on land

{
  "type": "neoorigins:breath_out_of_fluid",
  "fluid": "water",
  "name": "Dries Out",
  "description": "Suffocates when not in water."
}

Pair with neoorigins:water_breathing so the player never loses air underwater while the bubble row depletes on land.

---

neoorigins:biome_buff

Deprecated in 2.0: this type is now an alias for neoorigins:condition_passive. See MIGRATION.md.

Applies a status effect while the player is standing in a biome matching the given biome tag.

Field	Type	Required	Default	Description
biome_tag	Identifier	no	""	Biome tag, e.g. minecraft:is_forest. Not schema-required, but supply it in practice: the default is an empty tag, which matches no biome, so the buff never fires
effect	Identifier	no	minecraft:regeneration	Effect to apply, e.g. minecraft:speed
amplifier	int	no	0	Effect level

Example: Speed I in forests

{
  "type": "neoorigins:biome_buff",
  "biome_tag": "minecraft:is_forest",
  "effect": "minecraft:speed",
  "amplifier": 0,
  "name": "Forest Stride",
  "description": "Moves faster in forest biomes."
}

---

neoorigins:damage_in_biome

Deprecated in 2.0: this type is now an alias for neoorigins:condition_passive. See MIGRATION.md.

Deals periodic damage to the player while in a matching biome. Match by tag (biome_tag) or by an explicit list (biomes); damage fires once per second (the interval is fixed at 20 ticks).

Field	Type	Required	Default	Description
biome_tag	Identifier	no*	—	Biome tag to match, e.g. minecraft:is_nether. Use this or biomes.
biomes	array of Identifier	no*	—	Explicit biome IDs; matches if the player is in any of them. Use this or biome_tag.
damage_per_second	float	no	1.0	Damage applied each second
damage_type	string	no	generic	Damage type used for the hit

_{* Provide either biome_tag or biomes. If both are omitted the condition matches no biome.}

Example:

{
  "type": "neoorigins:damage_in_biome",
  "biome_tag": "minecraft:is_nether",
  "damage_per_second": 1.0,
  "name": "Nether Intolerance",
  "description": "Takes damage in the Nether."
}

---

neoorigins:burn_at_health_threshold

Deprecated in 2.0: this type is now an alias for neoorigins:condition_passive. See MIGRATION.md.

Ignites the player when their HP drops below a percentage of their maximum health.

Field	Type	Required	Default	Description
threshold_percent	float	no	0.25	HP fraction that triggers ignition (e.g. 0.25 = below 25%)
fire_ticks	int	no	60	Duration the player is set on fire

Example:

{
  "type": "neoorigins:burn_at_health_threshold",
  "threshold_percent": 0.25,
  "fire_ticks": 60,
  "name": "Critical Combustion",
  "description": "Catches fire when near death."
}

---

neoorigins:mobs_ignore_player

Causes specific mob types to ignore the player. By default a retaliation window applies: once the player hits the mob, the mob may target back briefly. Set passive: true to make the ignore unconditional.

Field	Type	Required	Default	Description
entity_types	list of Identifier or #tag	no	[]	Entity types that will ignore the player. Accepts raw ids ("minecraft:zombie") and tag references ("#minecraft:skeletons"). When empty, every mob ignores.
entity_blacklist	string[]	no	[]	Entity ids and tag refs this power never affects; they target the player normally even when entity_types matches (including the empty match-all case). Checked on top of the built-in exclusions below.
passive	bool	no	false	When true, the ignore is unconditional: even attacking the mob does not provoke retaliation.

Boss-tier mobs (the Warden, Ender Dragon and Wither) never ignore the player, regardless of entity_types (an empty match-all list won’t make the Warden docile). Server operators can extend that exclusion via the tame_scare_entity_blacklist config list (see Global taming/scare exclusions).

Example: only creepers ignore (with retaliation)

{
  "type": "neoorigins:mobs_ignore_player",
  "entity_types": ["minecraft:creeper"],
  "name": "Creeper Affinity",
  "description": "Creepers ignore you unless attacked."
}

Example: unprovokable peace with every skeleton (tag + passive)

{
  "type": "neoorigins:mobs_ignore_player",
  "entity_types": ["#minecraft:skeletons"],
  "passive": true,
  "name": "Bonewalker",
  "description": "Skeletons never see you as a threat, no matter what you do."
}

This is distinct from scare_entities (which makes mobs flee). mobs_ignore_player makes mobs neutral; scare_entities makes them run away.

---

neoorigins:mobs_target_player

The inverse of mobs_ignore_player: listed mob types proactively hunt a player who has this power, the way wolves hunt a vanilla skeleton. Nothing fires when a mob is not targeting the player, so this can not be a reactive event: instead each mob is given a targeting goal on spawn that acquires the nearest matching power-holder within range.

Field	Type	Required	Default	Description
entity_types	list of Identifier or #tag	no	[]	Entity types that hunt the player. Accepts raw ids ("minecraft:wolf") and tag references ("#minecraft:wolves"). When empty, every mob hunts the player.
entity_blacklist	string[]	no	[]	Entity ids and tag refs this power never affects; they never hunt the player even when entity_types matches (including the empty match-all case). Checked on top of the built-in exclusions below.
range	double	no	16.0	How far (in blocks) a matching mob can be and still start hunting the player. Also capped by the mob’s own follow range, so values above that have no extra effect.

Boss-tier mobs (the Warden, Ender Dragon and Wither) never hunt the player, regardless of entity_types. Server operators can extend that exclusion via the tame_scare_entity_blacklist config list (see Global taming/scare exclusions).

Example: a skeleton-type origin that wolves hunt

{
  "type": "neoorigins:mobs_target_player",
  "entity_types": ["minecraft:wolf"],
  "range": 20.0,
  "name": "Bonewalker's Curse",
  "description": "Wolves hunt you the way they hunt skeletons."
}

Pairs naturally with mobs_ignore_player: use mobs_ignore_player for the mobs that leave a skeleton alone, and mobs_target_player for the wolves that chase it.

---

neoorigins:no_mob_spawns_nearby

Suppresses mob spawns within a radius of the player. Toggleable: the player can turn the aura on/off via their skill keybind.

Field	Type	Required	Default	Description
radius	int	no	24	Radius in blocks within which spawns are suppressed. Note: vanilla already blocks MONSTER-category natural spawns within 24 blocks of any player (NaturalSpawner); use a value above 24 to extend the safe zone meaningfully.
categories	list of string	no	["monster"]	Spawn categories to suppress: monster, creature, ambient, water_creature, or all

Example: suppress hostile spawns in a 36-block radius

{
  "type": "neoorigins:no_mob_spawns_nearby",
  "radius": 36,
  "categories": ["monster"],
  "name": "Warding Presence",
  "description": "Hostile mobs don't spawn within 36 blocks. Toggle with skill key."
}

neoorigins:entity_group

Treats the player as a member of a mob group, so game mechanics that key off a creature’s type act on the player. A player can’t be added to vanilla’s real entity-type tags, so membership is simulated by intercepting the relevant hooks: effect immunity, instant heal/harm inversion, enchant vulnerability, and mob targeting.

Field	Type	Required	Default	Description
group	string	no	undefined	Group id. A bare name (no namespace) resolves to neoorigins:<name>. undefined means no classification.

Example:

{
  "type": "neoorigins:entity_group",
  "group": "undead",
  "name": "Undead Nature",
  "description": "Treated as an undead creature — immune to poison, healed by harm."
}

Built-in groups

These are registered in code and work with zero setup:

Group	Effect
neoorigins:undead	Immune to Poison and Regeneration; Instant Health harms and Instant Damage heals; takes extra damage from Smite.
neoorigins:arthropod	Takes extra damage from Bane of Arthropods (plus the vanilla slowness-on-hit).
neoorigins:water	Takes extra damage from Impaling.
neoorigins:illager	Raiders (anything in #minecraft:raiders) won’t target the player; village-spawned iron golems hunt the player (player-built golems stay loyal); villagers and wandering traders flee the player.
neoorigins:piglin	Piglins and piglin brutes never target the player. Unlike vanilla this is unconditional: no gold armor required.
neoorigins:skeleton	The undead kit (Poison/Regeneration immunity, inverted instant effects, Smite vulnerability) plus wolves hunt the player the way they hunt vanilla skeletons, and the player burns in daylight like a vanilla skeleton (honours the same [sun_damage] helmet/umbrella rules as exposed_to_sun).

Referencing an unknown group id (one with no built-in default and no datapack file) logs a one-time warning and does nothing, rather than silently no-op-ing.

Custom groups (datapack)

A datapack can mint new groups, or override a built-in, with a JSON file at data/<namespace>/neoorigins/entity_groups/<name>.json. A file whose id matches a built-in (e.g. data/neoorigins/neoorigins/entity_groups/undead.json) replaces that built-in. Every field is optional:

Field	Type	Default	Effect
immune_effects	list of effect ids	[]	These status effects can’t apply to the player.
invert_instant_effects	bool	false	Instant Health harms and Instant Damage heals (undead behaviour).
vulnerable_enchants	list of enchant ids	[]	For each listed enchant, the attacker’s weapon level adds bonus damage (level × 2.5 per enchant, summed). Listing minecraft:bane_of_arthropods also applies the vanilla slowness-on-hit.
ignored_by	list of entity ids and/or #tags	[]	Mobs matching these entries never target the player.
targeted_by	list of entity ids and/or #tags	[]	Mobs matching these entries proactively hunt the player, within ~16 blocks. Player-built iron golems are exempt even when minecraft:iron_golem is listed; only village-spawned golems hunt.
feared_by	list of entity ids and/or #tags	[]	Mobs matching these entries flee the player, within ~8 blocks.
burns_in_sunlight	bool	false	The player catches fire in daylight like a vanilla skeleton, honouring the same [sun_damage] config (helmet protection, neoorigins:sun_permeable helmets, umbrella) as the exposed_to_sun condition.

Example: data/mypack/neoorigins/entity_groups/cursed.json

{
  "immune_effects": ["minecraft:poison", "minecraft:wither"],
  "invert_instant_effects": true,
  "vulnerable_enchants": ["minecraft:smite"],
  "ignored_by": ["#minecraft:raiders", "minecraft:zombie"],
  "targeted_by": ["minecraft:iron_golem"],
  "feared_by": ["minecraft:villager", "minecraft:wandering_trader"]
}

An origin then opts in with {"type": "neoorigins:entity_group", "group": "mypack:cursed"}.

---

neoorigins:active_swap

Active ability that swaps positions with the entity the player is looking at: the nearest living entity on the look ray (hitboxes padded by 0.3). There is no line-of-sight check, so it targets through walls.

  "description": "Fires a wind charge that blasts nearby creatures back."
}

---

neoorigins:starting_equipment

Grants the player one or more items (optionally with enchantments) once on first origin assignment. Tracks grant state per-player so the items are not re-granted on respawn.

There are two shapes. The singular shape sets item at the root and grants one stack. The plural shape sets stacks and grants several. Pick one: they do not combine. See Singular vs plural below.

Field	Type	Required	Default	Description
grant_id	string	yes	—	Unique ID tracked so the bundle is granted only once per player. Dedups the whole power, not individual stacks.
stacks	list	no	[]	Plural shape: array of stack entries, each taking the same per-stack fields as the singular shape (item, count, enchantments, legacy_tag, components). Granted in array order.
item	Identifier	no	""	Singular shape: item to grant, e.g. minecraft:trident. Optional only when stacks is provided; one of the two must be present.
count	int	no	1	Singular shape: stack count
enchantments	list	no	[]	Singular shape: list of {"id": "...", "level": N} enchantment entries
legacy_tag	string	no	""	SNBT string for legacy NBT data (Potion, display.Name, etc.). Recognised keys are translated to data components; unrecognised keys go to minecraft:custom_data.
components	string	no	""	SNBT string representing a DataComponentPatch. Supports any registered data component (vanilla or modded). Parsed with registry context at grant time.

Example: enchanted trident

{
  "type": "neoorigins:starting_equipment",
  "grant_id": "abyssal_trident",
  "item": "minecraft:trident",
  "enchantments": [
    {"id": "minecraft:mending", "level": 1},
    {"id": "minecraft:unbreaking", "level": 3},
    {"id": "minecraft:riptide", "level": 3}
  ],
  "name": "Deep-Sea Armament",
  "description": "Begins life with an enchanted trident."
}

Example: modded item with custom data components (Iron’s Spellbooks)

{
  "type": "neoorigins:starting_equipment",
  "grant_id": "mage_spellbook",
  "item": "irons_spellbooks:iron_spell_book",
  "components": "{\"irons_spellbooks:spell_container\":{data:[{id:\"irons_spellbooks:firebolt\",index:1,level:1}],maxSpells:5,mustEquip:1b,spellWheel:1b}}",
  "name": "Arcane Tome",
  "description": "Begins life with a pre-inscribed spell book."
}

Example: a multi-item starting kit

{
  "type": "neoorigins:starting_equipment",
  "grant_id": "ranger_kit",
  "stacks": [
    {
      "item": "minecraft:bow",
      "enchantments": [{"id": "minecraft:power", "level": 2}]
    },
    {"item": "minecraft:arrow", "count": 32},
    {"item": "minecraft:leather_boots"}
  ],
  "name": "Ranger's Kit",
  "description": "Begins life with a bow, arrows and boots."
}

Singular vs plural

stacks does not add to the root item — it replaces it. When stacks is non-empty the root item, count, enchantments, legacy_tag and components are all ignored, so a power declaring both silently drops the root item. Put every item in stacks, or use the singular shape alone.

One grant_id covers the whole bundle. Two consequences worth planning around:

• The bundle is marked granted if at least one stack went in. If one item id is a registry miss — a typo, or a mod that is not installed — the rest still arrive and the bundle is sealed, so correcting the id later does not deliver the missing item to players who already have the bundle. Give a genuinely optional item its own power with its own grant_id.
• If every id fails, the bundle is deliberately left un-deduped, so fixing the typo and running /reload retries it.

A stack with a blank item is skipped with a warning rather than failing the power, so an unfilled row left behind in the in-game editor is tolerated.

/reload does not grant anything by itself: players who are already online receive a new or retried bundle on their next login, respawn or origin pick.

neoorigins:active_place_block

Active ability that places a specific block at the surface the player is looking at, up to a maximum range.

Field	Type	Required	Default	Description
block_id	Identifier	no	minecraft:glowstone	Block to place
max_distance	float	no	5.0	Maximum targeting range in blocks
cooldown_ticks	int	no	100	Cooldown in ticks
hunger_cost	int	no	0	Food points removed per use

Example:

{
  "type": "neoorigins:active_place_block",
  "block_id": "minecraft:glowstone",
  "max_distance": 5.0,
  "cooldown_ticks": 100,
  "name": "Stone Touch",
  "description": "Places a glowstone block where you're looking."
}

---

neoorigins:crop_harvest_bonus

Passively grants extra item drops when the player harvests a fully-grown crop or breaks a log. The bonus drops are identical copies of the block’s normal drops. Crops means CropBlock at max age (wheat, carrots, potatoes, beetroot and the like; not nether wart, cocoa, berries, melons or pumpkins). Logs means naturally grown logs, not stripped or player-placed ones.

Field	Type	Required	Default	Description
extra_drops	int	no	1	Number of extra drop copies per break

Example:

{
  "type": "neoorigins:crop_harvest_bonus",
  "extra_drops": 1,
  "name": "Bountiful Harvest",
  "description": "Crops and trees yield extra resources."
}

---

neoorigins:shadow_orb

Active ability that places a persistent shadow orb at the player’s position. Each orb applies Darkness and Blindness to nearby entities at a set interval, skipping the caster and their team allies. Orbs only pulse while their owner is in the same dimension, and placing an orb in a new dimension clears the old ones. The player can maintain up to max_orbs orbs at once; placing a new one when at the cap removes the oldest. Orbs are cleared when the origin is revoked.

Field	Type	Required	Default	Description
max_orbs	int	no	4	Maximum number of simultaneous orbs
radius	float	no	28.0	Effect radius per orb in blocks
cooldown_ticks	int	no	100	Cooldown between placements
tick_interval	int	no	20	Ticks between pulses per orb
hunger_cost	int	no	0	Food points removed per placement

Example:

{
  "type": "neoorigins:shadow_orb",
  "max_orbs": 4,
  "radius": 28.0,
  "cooldown_ticks": 100,
  "tick_interval": 20,
  "name": "Shadow Anchor",
  "description": "Places orbs that shroud the area in darkness."
}

---

neoorigins:persistent_effect

Generic condition-gated, toggleable status-effect stack. Part of the 2.0 consolidation: replaces status_effect, stacking_status_effects, night_vision, glow, water_breathing, breath_in_fluid, and the tag branch of regen_in_fluid with one type that applies an arbitrary list of mob effects whenever an optional condition (an EntityCondition DSL tree) is met.

Field	Type	Required	Default	Description
effects	list of EffectSpec	no	[]	Mob effects to apply. See below. May also be a single inline EffectSpec on the top-level object, which is read only when effects is absent or not an array. Not schema-required, but an empty list applies nothing.
condition	EntityCondition	no	always-true	DSL condition: effects only apply while it is true. Effects are cleared when it becomes false.
toggleable	bool	no	true	When true, this is an active-keybind power: pressing the key toggles effects on/off. When false, effects are always applied while condition is true.
default_off	bool	no	false	Toggleable powers only: when true, the power starts disabled, so effects stay off until the player first toggles it on.
effect	Identifier	no	—	Root-level single-effect shorthand, equivalent to a one-entry effects list. Read only when effects is absent. Alias id.
amplifier	int	no	—	Effect level for the root-level single-effect shorthand. With an effects array present it instead overrides the first effect’s amplifier — winning even over one that entry sets itself — which is how a server admin retunes strength without editing the array. Later specs are unchanged, and unlike its three neighbours below it does not cascade.
ambient	bool	no	true	Root default, cascaded onto every EffectSpec that omits it.
show_particles	bool	no	false	Root default, cascaded onto every EffectSpec that omits it.
show_icon	bool	no	true	Root default, cascaded onto every EffectSpec that omits it.

EffectSpec object:

Field	Type	Required	Default	Description
effect	Identifier	yes	—	Effect ID, e.g. minecraft:strength (alias id also accepted). A spec with a missing or unknown id is dropped without a log.
amplifier	int	no	0	Effect level
ambient	bool	no	true	Ambient particles (low visibility)
show_particles	bool	no	false	Whether to show particles
show_icon	bool	no	true	Whether to show the HUD icon

Root cascade: show_icon, show_particles, and ambient placed at the power root (alongside type/effects) cascade as defaults onto every nested EffectSpec that does not declare its own value. This lets you set HUD/particle visibility once for the whole stack instead of repeating it per effect.

minecraft:night_vision is special-cased. A spec granting night vision is skipped while either the disable_night_vision server config is set or the player has switched night vision off with the dedicated Toggle Night Vision keybind (default K). The gate is per effect, not per power, so a stack of water breathing + night vision + haste keeps applying the other two. Nothing is needed in the JSON for this. See neoorigins:night_vision.

Example: permanent always-on Weakness II

{
  "type": "neoorigins:persistent_effect",
  "effect": "minecraft:weakness",
  "amplifier": 1,
  "toggleable": false,
  "name": "Frail",
  "description": "Permanently weakened."
}

Example: Strength + Haste while in water (conditional, not toggleable)

{
  "type": "neoorigins:persistent_effect",
  "toggleable": false,
  "condition": { "type": "neoorigins:in_water" },
  "effects": [
    { "effect": "minecraft:strength", "amplifier": 0 },
    { "effect": "minecraft:haste",    "amplifier": 1 }
  ],
  "name": "Tidecaller",
  "description": "Empowered while immersed in water."
}

Effects are applied with infinite duration (MobEffectInstance.INFINITE_DURATION), so they never tick down or expire on their own. They are cleared when the condition becomes false, when the power is toggled off, or when the origin is revoked, and re-applied when the condition becomes true again. When toggleable is true (the default), the player can press their skill key to toggle effects on/off. Set toggleable: false for effects that should always be active, or default_off: true to start a toggleable power in the off state. A single effect can be specified inline on the top-level object (effect, amplifier, etc.) instead of using the effects list.

neoorigins:modify_food_nutrition

Overrides the nutrition (hunger) value of food the player eats. Matching food gives exactly the configured number of hunger points regardless of its original value. Saturation is scaled proportionally. Use food_item or food_tag to filter which foods are affected; if neither is set, ALL food is affected.

The override is applied at the moment of eating rather than written onto the item, so the item’s own food data is never changed. That is invisible in play but it matters to anything that reads the stack: with AppleSkin installed, NeoOrigins feeds the adjusted figures to AppleSkin’s tooltip and held-food preview so they agree with what eating will actually give. See COMPATIBILITY.md. Other mods that read DataComponents.FOOD off the stack directly will still see the vanilla value.

Field	Type	Required	Default	Description
nutrition	int	no	1	Fixed hunger points matching food gives
food_item	Identifier	no	—	Only affect this specific item (e.g. minecraft:sweet_berries)
food_tag	string	no	—	Only affect items in this tag (e.g. #minecraft:meat). Supports # prefix.

Example: all food gives 1 hunger point

{
  "type": "neoorigins:modify_food_nutrition",
  "nutrition": 1,
  "name": "Picky Eater",
  "description": "Gains almost no nutrition from food."
}

Example: meat gives 8 hunger points

{
  "type": "neoorigins:modify_food_nutrition",
  "nutrition": 8,
  "food_tag": "#minecraft:meat",
  "name": "Carnivore",
  "description": "Thrives on meat."
}

neoorigins:condition_passive

Generic condition-gated periodic action: “a passive with a trigger”. Part of the 2.0 consolidation: collapses biome_buff, damage_in_biome, damage_in_daylight, damage_in_water, burn_at_health_threshold, mobs_ignore_player, no_mob_spawns_nearby, and item_magnetism into a single type. Also supersedes tick_action when condition is omitted.

Field	Type	Required	Default	Description
interval	int	no	20	Tick interval between evaluations (clamped to ≥ 1)
condition	EntityCondition	no	always-true	DSL condition to test each interval
entity_action	EntityAction	no	noop	Action run against the player when condition is true
else_action	EntityAction	no	noop	Action run when condition is false
toggleable	bool	no	false	When true, binds a skill keybind that flips the periodic action on/off (chat feedback via neoorigins.toggle.on/off). While off the interval action never runs.
default_off	bool	no	false	Toggleable powers only: when true the power starts disabled so the player opts in via the keybind.

See EVENTS.md / the Apoli compat docs for the full condition and action DSL.

Example: take 1 damage every 2 seconds in the Nether

{
  "type": "neoorigins:condition_passive",
  "interval": 40,
  "condition": {
    "type": "neoorigins:in_tag",
    "tag": "minecraft:is_nether"
  },
  "entity_action": {
    "type": "neoorigins:damage",
    "amount": 1.0,
    "source": "fire"
  },
  "name": "Nether Intolerance",
  "description": "Burns while in the Nether."
}

neoorigins:action_over_time

A straight alias for neoorigins:condition_passive — same fields, same behaviour, remapped before any field is read. It exists because “run this action every N ticks” is the use the type is most often reached for, and condition is optional, so the name reads better when there is no gate at all. Prefer condition_passive in new packs; use this where an existing pack already spells it this way.

neoorigins:tick_action is not the type to reach for here: it ships no behaviour and dispatches nothing.

Field	Type	Required	Default	Description
interval	int	no	20	Tick interval between runs, 20 = 1 second (clamped to ≥ 1)
condition	EntityCondition	no	always-true	DSL condition tested each interval
entity_action	EntityAction	no	noop	Action run against the player when the condition is true
else_action	EntityAction	no	noop	Action run when the condition is false
toggleable	bool	no	false	When true, binds a skill keybind that flips the periodic action on/off. While off the interval action never runs
default_off	bool	no	false	Toggleable only: when true the power starts disabled so the player opts in via the keybind

Worked examples (periodic feed, periodic heal) are under Periodic feed / heal.

neoorigins:effect_over_time

Sustained aura type: one entity_action tree pulsed on an interval, in one of two modes via the activation field. An aura is a constant effect (usually an origins:area_of_effect radiating from the holder); a passive aura is always on with no cost, while an active aura is keybind-toggled and drains an upkeep each interval to stay up, switching itself off when you can’t pay. A passive aura can also be made toggleable (toggleable: true), still free, but with an on/off keybind. Active auras start off by default (opt-in); toggleable passives start on. (For one-shot, cooldown-gated abilities use active_ability instead; this type is specifically for auras.)

Field	Type	Required	Default	Description
activation	enum	no	passive	passive | active (toggle accepted as an alias for active). passive pulses entity_action every interval while granted, with no upkeep. active binds a keybind that toggles the aura on/off; while on it pulses every interval AND pays the upkeep. Unrecognised values fall back to passive.
toggleable	bool	no	false	Passive mode only: add a free on/off keybind (no upkeep). A toggleable passive starts on. Active auras are always toggleable and start off; this flag is ignored for them.
interval	int	no	20	Ticks between aura pulses and, in active mode, between upkeep charges (clamped ≥ 1).
condition	EntityCondition	no	always-true	Gate: entity_action pulses each interval only while it passes, else else_action. In active mode the upkeep is still charged while the aura is on, regardless of this gate.
entity_action	EntityAction	no	noop	Action pulsed on the player each interval, typically an origins:area_of_effect applying damage/effects to nearby entities. Inside an area_of_effect, damage, heal, apply_effect, clear_effect and spawn_particles run on each affected entity, so you can paint custom particles (and apply/strip status effects) on everyone the aura touches.
else_action	EntityAction	no	noop	Action pulsed each interval while condition is false.
hunger_cost	int	no	0	Active upkeep: food points drained each interval; the aura auto-disables when the holder can’t pay. 0 = a free on/off toggle. Ignored in passive mode.
resource_cost	string	no	""	Active upkeep: resource power id drained each interval; falls back to hunger_cost when resource bars are globally disabled. Ignored in passive mode.
resource_cost_amount	int	no	0	Active upkeep: amount of resource_cost drained each interval.
default_off	bool	no	mode-dependent	Override the initial on/off state of a toggleable aura. Default: active → off, toggleable passive → on. Ignored for plain (non-toggleable) passive auras.

See EVENTS.md / the Apoli compat docs for the full condition and action DSL.

Custom particles & status effects on affected entities. Put spawn_particles (and apply_effect/damage/heal/clear_effect) inside the area_of_effect’s entity_action to apply them to each entity the aura hits, at that entity’s position. Put spawn_particles outside (a sibling of the area_of_effect) to draw on the holder instead. To apply a potion effect without its swirling vanilla particles, use apply_effect with "show_particles": false.

Filtering who the aura affects. Set the area_of_effect’s entity_condition to control which entities are touched. Entity-general conditions filter mobs and players alike: entity_type: minecraft:player = players only; entity_type: "#minecraft:skeletons" = a tag group; target_group = a vanilla mob category; health/relative_health/has_effect/on_fire/living; and and/or/not of those (plus Apoli’s inverted: true). For example, wrap not { entity_type: minecraft:player } to scorch hostile mobs without burning your allies. See area_of_effect for the full list.

Example (active damage aura): toggle it on to scorch nearby mobs every second, draining 2 hunger per second to keep it up. The flame particles spawn on each burned entity (inside the area_of_effect), not on you

For a plain passive aura (always on, no cost, e.g. a constant self-healing field), set "activation": "passive" and drop the cost fields. For a toggleable passive (free, but with an on/off keybind, on by default), add "toggleable": true.

neoorigins:action_on_event

The 2.0 generic event hook: fires an action and/or applies a float modifier when a named player event occurs. Replaces 20+ bespoke Origins-Classes hook powers (better_enchanting, more_smoker_xp, crop_harvest_bonus, break_speed_modifier, natural_regen_modifier, action_on_kill, action_on_hit_taken, thorns_aura, knockback_modifier, hunger_drain_modifier, food_restriction, …) with one configurable type.

Field	Type	Required	Default	Description
event	string	yes	—	Event name (case-insensitive). See EVENTS.md for the full list.
condition	EntityCondition	no	always-true	DSL gate: the event only fires when this is true
entity_action	EntityAction	no	noop	Side-effect run when the event fires
modifier	FloatModifier or list	no	identity	Float modifier applied to the event’s numeric payload (for modifier-style events). Each entry is { "operation": ..., "value": ... }; a list applies in order. value defaults to 0 (amount is not read). Operations (case-sensitive): addition, add_base, add_base_early, add_total, add_total_early add value; multiplication, multiply_base_multiplicative, multiply_total_multiplicative multiply by value; multiply_base_additive, multiply_total_additive multiply by 1 + value; set / set_total replace with value; min_total caps at value; max_total floors at value. Any other operation, including multiply_base and multiply_total, is logged as defaulted to identity and leaves the payload unchanged.
block_condition	BlockCondition	no	—	Block-position gate for block events (block_break, block_place, block_use, bonemeal). Supports block/id, in_tag, and/or (aliases all_of/any_of), block_state, height, adjacent, and the positional offset wrapper (see below). On any other event a set block_condition never matches, so entity_action does not run there. The modifier path does not check it.
hands	string or list	no	—	Hand gate for interaction events (block_use, entity_use, villager_interact): only fire for the listed hands, "main_hand" and/or "off_hand". Use ["main_hand"] to stop a power double-firing (vanilla dispatches the right-click once per hand). Fails closed when the event carries no hand info; ignored on other events.
hand	string or list	no	—	Singular alias for hands, read only when hands is absent (Apoli’s action_on_block_use spelling).
item_condition	ItemCondition	no	—	Item gate for item-carrying events (item_use, item_use_finish, food_eaten, food_finished, item_pickup, block_use, entity_use, villager_interact): only fire when the stack the event carries matches. That is the used, eaten or picked-up stack for the first five and the stack in the interacting hand for the rest, which is what Apoli’s item_condition on action_on_block_use / action_on_entity_use translates to. Takes the same Apoli item-condition shapes as equipped_item (id/tag/nbt/enchantment, with and/or/not). Fails closed when set but the event carries no item, including on events that never carry one; the modifier path does not check it.
effect	id	no	—	effect_applied only: pre-dispatch filter on this exact effect id.
effect_tag	tag id	no	—	effect_applied only: pre-dispatch filter on this effect tag (leading # optional). OR-matched with effect.
immunity_ticks	int ≥ 0	no	0	effect_applied only: after a successful cancel, grant this many ticks of full immunity to the same effect id before re-rolling.
power	id or list	no	—	power_activated only: pre-dispatch filter on the activated power’s id (single id or array). Omit to fire on any activation.
cooldown_ticks	int ≥ 0	no	0	After entity_action fires, suppress further firings of this power for this many ticks (20 = 1s). Tracked per player per power instance and persisted across respawn/relog. Only gates the action path: modifier chains are unaffected.

The offset block-condition wrapper. Inside block_condition, { "type": "neoorigins:offset", "x": 0, "y": -2, "z": 0, "condition": { ... } } evaluates its nested block condition at the event’s block position shifted by the given block offsets, the Apoli structural wrapper for checks like “a basin two blocks below the block I clicked”. Without a nested condition it matches all blocks (warned at load). The same wrapper works in block_collision and the area_of_effect block fan-out.

Block-condition types. Every field documented as a BlockCondition (block_condition here, in block_collision, in_block, in_block_anywhere, near_block, on_block, prevent_sleep and the area_of_effect block fan-out) accepts the same set of nested types:

Type	Fields	Matches when
block	block (or legacy id)	The block is exactly that id.
in_tag	tag	The block is in that block tag (leading # optional).
and / all_of / or / any_of	conditions	All / at least one nested condition matches.
offset	x, y, z, condition	The nested condition matches at the shifted position.
block_state	property, plus value/enum or comparison+compare_to	The block carries that blockstate property and its value matches. A block without the property never matches.
height	comparison (default >=), compare_to	The block’s own Y level compares true; { "comparison": "<=", "compare_to": 63 } is “at or below sea level”.
adjacent	adjacent_condition, comparison (default >=), compare_to (default 1)	The number of the six face-neighbours satisfying adjacent_condition compares true.

Any node also honours "inverted": true, which negates just that node.

{ "type": "neoorigins:adjacent",
  "adjacent_condition": { "type": "neoorigins:in_tag", "tag": "minecraft:ice" },
  "comparison": "<=",
  "compare_to": 2 }

{ "type": "neoorigins:block_state", "property": "waterlogged", "value": true }

Event categories (see EVENTS.md for the full list):

• Lifecycle: GAINED, LOST, CHOSEN, POWER_ACTIVATED, RESPAWN, DEATH, DIMENSION_CHANGE, ADVANCEMENT_EARNED
• Combat: ATTACK, HIT_TAKEN, HIT_DEALT, KILL, PROJECTILE_HIT, MOD_KNOCKBACK
• Food: FOOD_EATEN, FOOD_FINISHED, MOD_EXHAUSTION, MOD_NATURAL_REGEN, MOD_FOOD_NUTRITION, MOD_CRAFTED_FOOD_SATURATION
• Mining / blocks: BLOCK_BREAK, BLOCK_PLACE, BLOCK_USE, BONEMEAL, MOD_HARVEST_DROPS, MOD_BONEMEAL_EXTRA
• Crafting / stations: CRAFT_ITEM, SMELT_ITEM, ENCHANT_ITEM, ANVIL_REPAIR, MOD_CRAFT_AMOUNT, MOD_ENCHANT_LEVEL, MOD_ANVIL_COST
• Trading: TRADE_COMPLETED, VILLAGER_INTERACT, MOD_TRADE_PRICE
• Animals: BREED, TAME
• Items / interaction: ITEM_USE, ITEM_USE_FINISH, ITEM_PICKUP, ENTITY_USE
• Movement: JUMP, LAND, CLIMB, WAKE_UP, TICK, MOD_TELEPORT_RANGE, MOD_FALL_DAMAGE
• Other modifiers: MOD_POTION_DURATION
• Status effects: EFFECT_APPLIED

For action-style events set entity_action; for modifier-style events set modifier. A single power may declare both: the action path fires on dispatch sites and the modifier path chains on dispatchModifier sites.

neoorigins:cancel_event support. Using cancel_event as the entity_action vetoes the underlying game event, but only where NeoForge exposes a cancellable event:

• Cancellable: death (the lethal blow is undone; if the player is still at 0 HP they are left at 1 HP, totem-style; pair with a condition or a healing entity_action, otherwise the next damage tick kills them again), kill (spares the victim, same 1-HP patch), hit_taken (negates the incoming damage), attack (stops the swing before damage), land (negates fall damage), projectile_hit (negates the impact), item_use, food_eaten (blocks the use/eat), effect_applied (blocks the effect), block_break, block_place, block_use, entity_use, villager_interact, breed, tame, bonemeal.
• Not cancellable (the NeoForge event fires after the fact or cannot be cancelled; cancel_event is a silent no-op): jump, item_use_finish, food_finished, item_pickup, craft_item, smelt_item, enchant_item, anvil_repair, trade_completed, advancement_earned, wake_up, respawn, dimension_change, climb, tick, gained, lost, chosen, power_activated, and all mod_* modifier events.

Example: heal 1 heart on kill only while holding a wooden sword

{
  "type": "neoorigins:action_on_event",
  "event": "kill",
  "condition": {
    "type": "neoorigins:equipped_item",
    "equipment_slot": "mainhand",
    "item_condition": { "id": "minecraft:wooden_sword" }
  },
  "entity_action": {
    "type": "neoorigins:heal",
    "amount": 2.0
  },
  "name": "Wooden Vampire",
  "description": "Regain health on kills, but only with a wooden sword."
}

Example: 30% faster natural regen

{
  "type": "neoorigins:action_on_event",
  "event": "mod_natural_regen",
  "modifier": {
    "operation": "multiplication",
    "value": 1.3
  }
}

Example: 90% probabilistic resistance to a third-party infection effect, with 2s of full immunity after each cleanse

{
  "type": "neoorigins:action_on_event",
  "event": "effect_applied",
  "effect": "spore:mycelium_ef",
  "entity_action": {
    "type": "neoorigins:chance",
    "chance": 0.9,
    "action": { "type": "neoorigins:cancel_event" }
  },
  "immunity_ticks": 40
}

Imported origins:action_on_block_use and origins:bonemeal powers translate to this type automatically (events block_use and bonemeal), the same way origins:action_on_block_break and origins:action_on_entity_use already do. The translation carries condition, block_condition and the hand filter over directly; block_action and entity_action both run as the event’s entity_action (block actions self-resolve the clicked/bonemealed block from the event context), and an Apoli action_result of SUCCESS/CONSUME/CONSUME_PARTIAL/FAIL appends a cancel_event so the interaction outcome matches.

---

neoorigins:invulnerability

Native invulnerability power: cancels incoming damage whose source matches any configured filter. If every filter list is empty, blocks all incoming damage. Replaces the lossy 1.x translation that only covered FIRE.

Field	Type	Required	Default	Description
damage_types	list of string	no	[]	Damage type IDs (e.g. minecraft:fall), matched by ID
damage_tags	list of string	no	[]	Damage type tag IDs (e.g. minecraft:is_fire)
msg_ids	list of string	no	[]	Vanilla damage msgId strings (e.g. inFire, fall), covers loose Origins-style names

Filters combine with OR: a damage source is cancelled if it matches any entry in any list. If all three lists are empty, all damage is cancelled (matching Origins’ behaviour when damage_condition is omitted).

Example: fire and lava immunity

{
  "type": "neoorigins:invulnerability",
  "damage_tags": ["minecraft:is_fire"],
  "name": "Inferno Blood",
  "description": "Immune to fire and lava."
}

Example: block everything

{
  "type": "neoorigins:invulnerability",
  "name": "Adamant",
  "description": "Cannot be harmed."
}

---

neoorigins:size_scaling

Scales the player’s visual and collision size via the minecraft:generic.scale attribute. Optionally also scales block/entity interaction reach. The scale is not mirrored into Pehkui. Applied when the power is granted, so a top-level condition does not gate it.

Field	Type	Required	Default	Description
scale	float	no	1.0	Target scale multiplier (0.5 = half size, 2.0 = double)
modify_reach	bool	no	true	Also adjust block/entity interaction reach proportionally
reach_bonus	float	no	0.0	Flat reach (blocks) added to both block and entity interaction range, on top of any modify_reach scaling

Example: half-size origin that keeps usable reach

{
  "type": "neoorigins:size_scaling",
  "scale": 0.5,
  "modify_reach": false,
  "reach_bonus": 0.5,
  "name": "Tiny",
  "description": "Half-sized, but reach is kept near normal."
}

The scale attribute uses ADD_VALUE against a base of 1.0 (so delta = scale - 1.0); proportional reach (modify_reach) uses ADD_MULTIPLIED_BASE so reach tracks visual size, while reach_bonus uses a flat ADD_VALUE on both ranges. Missing attributes (older MC or NeoForge versions) are skipped silently, without a warning.

For the bundled size origins, scale, modify_reach and reach_bonus are all exposed per-origin in config/neoorigins/power_overrides.toml, so server owners can retune a shrunk origin’s reach without a datapack; small origins (inchling_size, tiny_size) ship with modify_reach: false and a positive reach_bonus so they stay playable out of the box.

Size stacks across layers. Every size_scaling power owns its own modifier ids, so an origin scaling to 1.3 and a class scaling to 1.25 leave the player at 1.55, not at whichever layer was picked last. Re-picking one layer removes only that layer’s contribution and leaves the rest standing, in either order. Reach modifiers follow the same rule. If you want two layers to be mutually exclusive rather than cumulative, gate them with conditions; do not rely on one overwriting the other.

Deleting or renaming a size power’s JSON is still safe: its leftover modifiers are swept the next time the player’s powers change, so a power that no longer exists cannot strand someone at the wrong size.

---

neoorigins:pose

Holds the player’s body in a chosen pose for as long as the power is on: prone (crawling), sneak height, or upright. Vanilla recomputes the pose every tick and would fight a one-off change, so this is a power rather than an action — it re-asserts the pose while the origin says so and releases it the moment it stops.

Field	Type	Required	Default	Description
pose	string	yes	—	standing, crouching or swimming (case-insensitive). Any other value makes the whole power fail to load, with an error naming the three it accepts: there is no fallback to standing, so a typo is loud rather than a power that silently does nothing
toggleable	bool	no	true	Binds a keybind that flips the pose on and off
default_off	bool	no	false	Toggleable powers only: the pose starts released, so the player opts in via the keybind
enabled	bool	no	true	Kill switch: when false the power stays attached but holds no pose
cooldown_icon	string	no	""	Item id or .png path shown on the HUD ability cluster: full-bright while on, dimmed while off
always_show_icon	bool	no	false	Keep the icon on the cluster while the power is idle

Example: a burrowing origin that crawls on command

{
  "type": "neoorigins:pose",
  "pose": "swimming",
  "toggleable": true,
  "default_off": true,
  "cooldown_icon": "minecraft:dirt",
  "name": "Burrow",
  "description": "Drop prone to squeeze through a one-block gap."
}

swimming is the crawl pose: a 0.6x0.6 body with the eye at 0.4. The pose is not clearance-checked, so it fits wherever its box fits, including gaps the player could not otherwise enter — a crawling origin can pass under a one-block ceiling anywhere, not only where vanilla would let it. That is deliberate; narrow it with a condition if your pack wants it narrower. Releasing the pose hands the player back to vanilla, which does check clearance and settles on whatever fits where they are standing.

What the pose does and does not change. It sets the hitbox and the animation, and it costs speed: vanilla scales movement input by the minecraft:sneaking_speed attribute whenever the player is crouched or crawling, and that test reads the pose, so a forced crouching or a forced swimming on land walks at sneak pace. It does not set the sneak flag, so there is no ledge-stop and no quiet footsteps — hold pose: crouching and the player still walks off edges. It also does not grant swimming: the swim propulsion in travel runs off the separate swimming flag, which vanilla sets from sprinting in water and never from a pose, so a forced swimming out of water is a crawl and nothing more.

Two pose powers active at once resolve smallest-first (swimming, then crouching, then standing), so the winning pose always fits wherever the loser would have. The top-level condition gates the pose like any other passive: while it fails the player is released to their normal pose, and picks it back up when the condition returns.

sleeping, fall_flying and spin_attack are vanilla poses too, but each carries behaviour the pose alone does not deliver (a bed, an elytra, a trident), so they are not offered here. For gliding, use neoorigins:elytra_flight or neoorigins:natural_glide.

---

neoorigins:entity_set

Pure data-holder power. Its presence in a player’s active power set declares that the player participates in a named UUID set. Actual set storage lives on PlayerOriginData; the neoorigins:in_set / neoorigins:add_to_set / neoorigins:remove_from_set verbs read and mutate it.

Field	Type	Required	Default	Description
name	string	no	""	Name of the UUID set this power declares. Conventionally namespaced like mypack:kill_streak.

Example:

{
  "type": "neoorigins:entity_set",
  "name": "mypack:hunted",
  "description": "Tracks entities marked as hunted by this origin."
}

The colon in name is allowed and carries no mechanical meaning; it’s a soft convention for avoiding collisions between packs. Pair this with action_on_event (to add entries) and condition_passive or direct DSL predicates (to query membership).

---

neoorigins:enhanced_vision

Status (2.2.x): active again. On 26.x the brightness boost is applied through the lightmap render state (LightmapRenderStateExtractor mixin) at higher priority, so it survives other mods (Alex’s Caves, etc.) that touch the same pipeline. A handful of built-in powers (Avian keen sight, the Archer / Cleric / Miner class sights) use enhanced_vision; most origin night vision remains on neoorigins:night_vision.

Passive low-light vision: emits an enhanced_vision capability tag and scales the client brightness curve directly via a lightmap mixin (LightmapRenderStateExtractor). Unlike the full minecraft:night_vision status effect, there’s no screen tint, HUD icon, or max-brightness ramp at end of duration, just exposure-style compensation.

Field	Type	Required	Default	Description
exposure	float (0.0–1.0)	no	0.7	Target brightness scalar (advisory: the client mixin currently hardcodes 0.7; a real Night Vision effect still wins where stronger)

Example:

{
  "type": "neoorigins:enhanced_vision",
  "exposure": 0.7,
  "name": "Cat Eyes",
  "description": "Sees clearly in dim light without the green tint."
}

All exposure work happens on the logical client; the server only publishes the capability tag. If per-origin variance is needed later, the value will be wired through a client-synced power-config payload.

The Toggle Night Vision keybind (default K) switches this off too, so the key means the same thing whichever mechanism an origin uses. Like the status-effect path it starts on, so nothing changes for a player who never presses it. No ability slot is claimed either way: the dedicated key sits outside the skill-slot system entirely. See neoorigins:night_vision.

---

neoorigins:edible_item

Makes arbitrary non-food items edible. A matching item plays the normal 32-tick eating animation; when it finishes, the configured nutrition/saturation is applied, one is removed from the stack, and an action_on_event.ITEM_USE_FINISH dispatch fires with the stack as context. Items that are already food keep their vanilla values: the configured nutrition, saturation and consume_sound are ignored for anything that has a food component (raw fish, rotten flesh).

Field	Type	Required	Default	Description
items	list of Identifier	no	[]	Exact item IDs that qualify
tags	list of Identifier	no	[]	Item tag IDs that qualify
tiers	list of Tier	no	[]	Value bands inside the set; see below
nutrition	int	no	4	Food points restored (1 shank = 2)
saturation	float	no	0.3	Saturation restored
always_edible	bool	no	true	If true, can be eaten at full hunger
consume_sound	Identifier	no	(none)	Optional sound ID played on consume

At least one of items, tags or tiers should be non-empty, otherwise nothing will ever match. Matching is inclusive: an item qualifies if it appears in any of the three.

Eligibility follows the game’s own rule for food (always_edible, or an unfilled hunger bar, or creative and spectator mode), so a matching item eats in creative exactly as bread does. Creative also keeps the stack, the same way vanilla food does.

Tiers

A tier gives one part of the set its own values without splitting the power in two. Each entry is an object:

Field	Type	Required	Default	Description
items	list of Identifier	no	[]	Exact item IDs in this band
tags	list of Identifier	no	[]	Item tag IDs in this band
nutrition	int	yes	(none)	Food points for this band
saturation	float	no	(inherits)	Saturation for this band

The first tier whose items or tags match wins; an item matching none of them falls back to the power’s own nutrition and saturation. Order matters, so put the narrow bands first. Tiers match on top of the top-level lists rather than inside them, so a tier can introduce items the power never otherwise mentions.

Leave saturation off unless you mean to change it. Saturation is restored as nutrition × saturation × 2, so a tier that doubles both ends up granting four times the saturation, which is almost never what was intended.

}

Caveborn diet tags

The Caveborn’s seven eating powers each read one shipped item tag, so a datapack can extend any of them without overriding the power. A tag file lives under the namespace of the tag it extends, not your own, so declare data/neoorigins/tags/item/<name>.json inside your pack with "replace": false and append your own items.

Tag	Backing power	Nugget	Base	Block
neoorigins:caveborn_eat_stone	Stone Eater	(none)	2 / 0.4	(none)
neoorigins:caveborn_eat_copper	Copper Palate	(none)	3 / 0.6	6 / 0.6
neoorigins:caveborn_eat_iron	Iron Palate	1 / 0.0	4 / 0.8	8 / 0.8
neoorigins:caveborn_eat_gold	Gilded Palate	1 / 0.0	5 / 1.0	10 / 1.0
neoorigins:caveborn_eat_diamond	Diamond Palate	(none)	6 / 1.2	12 / 1.2
neoorigins:caveborn_eat_emerald	Emerald Palate	(none)	7 / 1.4	14 / 1.4
neoorigins:caveborn_eat_netherite	Netherite Palate	(none)	8 / 1.6	16 / 1.6

The three columns are tiers on each power. The base column is what an ingot, gem, raw material or ore is worth; the block column covers both the refined and the raw storage block; the nugget column exists only where the material has a nugget. Adding an item to a tag makes it edible at that tag’s base values unless it also falls inside one of the tiers, and the tiers read the c: tags rather than the neoorigins: one, so a modded iron block dropped into caveborn_eat_iron is worth eight only if it also registers in c:storage_blocks/iron or c:storage_blocks/raw_iron, and four if it does not. To grant an amount none of the bands cover, write your own edible_item power instead.

Every one of these powers is always_edible: false, so none of them go down on a full hunger bar.

The seven tags are built out of NeoForge’s c: common tags rather than lists of vanilla item ids, so a modded metal or stone that registers itself in the usual places is eaten without the pack doing anything. The six metal and gem tags take the material’s ingots/, nuggets/, gems/, raw_materials/, ores/ and storage_blocks/ entries, which is what pulls in deepslate ore variants, nether gold ore and ancient debris. Three literal ids are left in the set. netherite_scrap is one, because NeoForge publishes no common tag for the item itself: its c:ores/netherite_scrap covers ancient debris, the ore block. The other two are on caveborn_eat_stone, which is #c:stones plus #c:cobblestones plus basalt and blackstone, and carries no ore at all.

Each material also has a bonus power that fires on finishing the meal, and those are tiered the same way: a nugget grants fifteen seconds, the base form grants the listed duration, and a block grants three times it. Copper is Water Breathing I for sixty seconds, iron Haste I for sixty, gold Speed I for two minutes, diamond Luck II for five, emerald Fire Resistance for five, and netherite Strength I with Resistance I for five. A block is worth twice the food and three times the duration rather than the nine you would get from crafting it apart, since hunger caps at twenty and the extra food would be thrown away. Each meal additionally drives a hidden model_color tint for as long as its effect runs, though that tint is not drawn on 26.1 or 26.2 (see neoorigins:model_color); those six tints are individually switchable from power_overrides.toml.

Worth knowing for the ore and stone entries: both are placeable blocks, so aiming at a surface places one as normal. Eating one means aiming where it cannot be placed — the same rule the stone diet has always followed.

neoorigins:restrict_armor

Prevents certain items from being equipped in certain slots. When a matching item is placed in a restricted slot, the power ejects it back to the player’s inventory (or drops it to the ground if inventory is full).

Field	Type	Required	Default	Description
restrictions	list of SlotRestriction	no	[]	Per-slot filters. An empty list disables the power.

SlotRestriction object:

Field	Type	Required	Description
slot	string	yes	One of mainhand, offhand, head, chest, legs, feet, body
item	Identifier	no	Exact item ID to restrict
tag	Identifier	no	Item tag to restrict

If neither item nor tag is set on a restriction entry, any non-empty stack in that slot is restricted.

Example: no iron or diamond chestplates

{
  "type": "neoorigins:restrict_armor",
  "restrictions": [
    { "slot": "chest", "item": "minecraft:iron_chestplate" },
    { "slot": "chest", "item": "minecraft:diamond_chestplate" }
  ],
  "name": "Light Armor Only",
  "description": "Cannot wear iron or diamond chestplates."
}

Armor classes

NeoOrigins ships two item tags that categorize vanilla armor into light and heavy classes. Use these with restrict_armor to broadly gate what an origin can wear without listing every item individually.

Tag	Contents
neoorigins:light_armor	Leather, Chainmail (all slots)
neoorigins:heavy_armor	Iron, Gold, Diamond, Netherite (all slots)

Example: restrict an origin to light armor only

{
  "type": "neoorigins:restrict_armor",
  "restrictions": [
    { "slot": "head",  "tag": "neoorigins:heavy_armor" },
    { "slot": "chest", "tag": "neoorigins:heavy_armor" },
    { "slot": "legs",  "tag": "neoorigins:heavy_armor" },
    { "slot": "feet",  "tag": "neoorigins:heavy_armor" }
  ],
  "name": "Light Armor Only",
  "description": "Cannot wear heavy armor."
}

Adding modded armor to a class:

Modpack authors can extend the classes in two ways:

1. Datapack: add entries to the neoorigins:heavy_armor or neoorigins:light_armor item tags via a higher-priority datapack.

2. Config: add item IDs or #tags to the [armor_classes] section in config/neoorigins/gameplay.toml.

[armor_classes]
    # Items/tags added here supplement the neoorigins:heavy_armor tag
    heavy_armor = ["modid:steel_chestplate", "#modid:titanium_armor"]
    # Items/tags added here supplement the neoorigins:light_armor tag
    light_armor = ["modid:cloth_robe"]

Config entries are checked alongside the tags; items in either source count as that armor class.

neoorigins:restrict_items

One modular, multipurpose gate over equipping and using items. A single flexible power that covers both blacklist and allow-list semantics for any item matched by a reusable item condition, across any equipment slot and/or hand. Unlike restrict_armor (equip-only), this can also cancel item use, and, done properly, that means stopping a totem of undying from saving the holder (vanilla consumes the totem before the death event, so this is enforced via a mixin into checkTotemDeathProtection).

Field	Type	Required	Default	Description
item_condition	item condition	no	matches all	Apoli-style item condition (id / tag / nbt / enchantment / empty, with and/or/not composition) selecting which stacks the gate matches. Omit to match every stack.
slots	list of strings	no	[] (all)	EquipmentSlot names the equip gate applies to: mainhand, offhand, head, chest, legs, feet, body. Empty = all slots.
hands	list of strings	no	[] (both)	InteractionHand names the use gate applies to: mainhand, offhand. Empty = both hands.
prevent_equip	boolean	no	false	When true, equipping a matched item into a gated slot is rejected (ejected back to the inventory).
prevent_use	boolean	no	false	When true, using a matched item (right-click / raise: shields, totems, bows, food, …) in a gated hand is cancelled, including stopping a totem of undying from popping.
deny	boolean	no	true	true = blacklist: matched items are forbidden. false = allow-list: ONLY matched items are permitted for the gated action; everything else is forbidden.
condition	EntityCondition	no	always true	Optional whole-power gate: the power is inert unless it passes.

The single decision is match → forbidden: in blacklist mode a matched item is forbidden; in allow-list mode an unmatched item is forbidden. The same decision drives equip, use, and the totem mixin, so they can never disagree.

Example: a “fragile” origin can’t use shields and can’t be saved by totems

{
  "type": "neoorigins:restrict_items",
  "item_condition": {
    "type": "neoorigins:or",
    "conditions": [
      { "item": "minecraft:shield" },
      { "item": "minecraft:totem_of_undying" }
    ]
  },
  "prevent_use": true,
  "deny": true,
  "name": "Fragile",
  "description": "Cannot raise a shield, and a totem of undying will not save you."
}

Example (allow-list): can only ever hold a wooden sword in the main hand

{
  "type": "neoorigins:restrict_items",
  "item_condition": { "item": "minecraft:wooden_sword" },
  "slots": ["mainhand"],
  "prevent_equip": true,
  "deny": false,
  "name": "Pacifist's Vow",
  "description": "Refuses to wield anything but a wooden sword."
}

---

neoorigins:keep_inventory

On death, selectively retain inventory items matching the power’s filters. Matching items are removed from drops and restored on respawn into the exact slot they were taken from, trinket slots included: armour comes back worn, the hotbar keeps its layout, and a full inventory can no longer push the leftovers onto the ground.

Field	Type	Required	Default	Description
slots	list of string	no	["*"]	Slot categories to keep from: hotbar, main, armor, offhand, all (alias *). main also includes hotbar. Also accepts trinket slots: curio, accessory, or trinket cover every Curios slot, or name a specific slot id like ring or necklace.
items	list of Identifier	no	[]	Specific items to keep
tags	list of Identifier	no	[]	Item tags to keep

If both items and tags are empty, every item in the configured slots is kept.

Curios: trinket slots are covered when the Curios mod is installed; without it these slot tokens simply match nothing. The wildcard */all includes trinkets too.

A kept trinket is re-equipped into its original slot on respawn. Curios rebuilds its slot counts on its own schedule after a respawn, so if the slot isn’t writable yet the trinket is held and retried for three seconds rather than given up on. Only once that window is spent does it fall back to the regular inventory, and to the ground only if the inventory is full as well. Logging out mid-retry settles it the same way instead of losing it.

Example: always keep tools

{
  "type": "neoorigins:keep_inventory",
  "slots": ["main", "hotbar", "offhand"],
  "tags": ["minecraft:pickaxes", "minecraft:swords", "minecraft:axes", "minecraft:shovels"],
  "name": "Tool Preservation",
  "description": "Tools are never dropped on death."
}

---

neoorigins:modify_player_spawn

Overrides the player’s respawn location to a power-configured target. Unlike the origin’s spawn_location (first-join and bed-less respawn only), this power fires on every respawn except the one after leaving the End. The teleport lands a tick or more after the respawn. Optionally also overrides the bed/respawn-anchor spawn point.

Field	Type	Required	Default	Description
location	LocationCondition	yes	—	Target location descriptor: dimension / biome / biome_tag / structure / structure_tag. See attribute_modifier’s location_condition for the shape.
override_bed	bool	no	false	When true, also overrides bed/respawn-anchor spawn. When false, respects a valid bed/anchor and only fires if none is set.

Example: always respawn in an End city

{
  "type": "neoorigins:modify_player_spawn",
  "location": {
    "dimension": "minecraft:the_end",
    "structure": "minecraft:end_city"
  },
  "override_bed": true,
  "name": "Void-Bound",
  "description": "Always respawns in the nearest End city."
}

---

neoorigins:toggle

A bare, stateless boolean power: purely a data-holder whose state lives in CompatAttachments.toggleState() keyed by the registered id. Unlike active_ability, toggle does not consume a keybind slot; it’s a named boolean other powers gate on.

Field	Type	Required	Default	Description
default	bool	no	false	Value reads see before the toggle has ever been flipped on this player. Set true for “on until flipped off.”

Read the current value with neoorigins:power_active { power: "mypack:my_toggle" }. Flip it with neoorigins:toggle { power: "mypack:my_toggle" } (optionally value: true/false to set explicitly).

Example:

{
  "type": "neoorigins:toggle",
  "default": false,
  "hidden": true,
  "name": "Hunter's Mark",
  "description": "Internal flag gated by other powers."
}

hidden: true keeps the toggle out of the origin info panel, recommended for any purely-internal flag a player doesn’t need to see listed.

This type takes no key. A key on a neoorigins:toggle is ignored: the type is not an active power, so no keypress can reach it. To put a toggle on a hotkey, keep the flag here and give the key to a neoorigins:active_ability whose entity_action is neoorigins:toggle { power: "mypack:my_toggle" }. The Apoli-style origins:toggle is a different type and does accept key.

See COOKBOOK.md → Toggleable abilities (no keybind slot) for full recipes.

neoorigins:active_ability

Generic cooldown-gated active (keybind) ability. Part of the 2.0 consolidation: collapses active_teleport, active_dash, active_launch, active_recall, active_swap, active_fireball, active_bolt, active_phase, active_place_block, healing_mist, repulse, active_aoe_effect, and others into one type whose effect is described by an entity_action tree.

Field	Type	Required	Default	Description
cooldown_ticks	int	no	60	Cooldown after each use. Ignored when cooldown_resource is set.
cooldown_resource	string	no	""	Id of a neoorigins:variable (or neoorigins:resource) counter whose live value, in ticks, is read at activation time and used as the cooldown length, overriding cooldown_ticks. Empty = fixed cooldown. Edit the counter with change_resource/set_resource to make a power’s cooldown scale with game state (stacks consumed, upgrades bought, etc.). A missing counter falls back to its declared start; negative values clamp to 0 (instant reuse).
hunger_cost	int	no	0	Food points removed per use (1 shank = 2 points). Silently aborts if player has less food (cooldown not consumed).
resource_cost	string	no	""	Id of a neoorigins:resource power to debit per use. Empty = no resource cost.
resource_cost_amount	int	no	0	Amount drained from resource_cost per use. Silently aborts (cooldown not consumed) if the resource can’t cover it. If resource bars are globally disabled in config, the cost is charged as hunger instead.
entity_action	EntityAction	no	noop	Action tree fired on use (typically neoorigins:and { actions: [...] })
condition	EntityCondition	no	always-true	DSL gate: skips firing (and the cooldown) if false
fail_action	EntityAction	no	—	Run when an activation attempt is blocked by condition, e.g. a tellraw telling the player why. Not fired on cooldown or hunger/resource aborts; the blocked attempt never consumes the cooldown.
cooldown_icon	string	no	""	HUD cooldown icon (item id or .png texture path), see “Cooldown HUD fields” at the top of this page
cooldown_countdown	bool	no	true	Draw remaining seconds on the icon (needs cooldown_icon)
always_show_icon	bool	no	false	Keep the icon on the HUD even while idle (needs cooldown_icon; this is what keeps the icon visible under the default COOLDOWNS_AND_TOGGLES HUD mode, and has no additional effect under ALL_ACTIVE_ABILITIES)
key	int, string, or object	no	—	Hotkey the ability binds to instead of a skill_1..skill_6 slot. A number N pins it to named-hotkey pool slot “Hotkey N” (1-64), and several powers sharing the same N all fire from that one key. A string is a keybind translation key used as-is ("examplepack.key.leap"), or a vanilla input key such as "key.jump", which binds straight to that game control. An object takes {"key": <number or string>, "continuous": true} to fire every tick the key is held. Omit for the next free skill slot. See Named keybinds.

Each active_ability power maintains an independent cooldown. Multiple active abilities on the same origin do not share a cooldown counter: triggering one ability does not block another.

Named hotkey slots: with no key field, neoorigins:active_ability takes one of the six hardcoded key.neoorigins.skill_1..skill_6 controls. Declare a key and it binds to that instead and is kept out of the skill-slot roster, so the six stay free for the abilities that need them. This works on the native type directly: you do not have to fall back to an Apoli-style origins:active_self to get a labelled hotkey. See Named keybinds.

Actions and conditions are compiled once at power-load time via ActionParser / ConditionParser; runtime only dispatches through the compiled closures.

Hunger gating is handled at the AbstractActivePower base class level: when hunger_cost > 0, the base checks and debits food before calling execute. Any power that extends AbstractActivePower and wires hungerCost() through its Codec inherits the behavior automatically.

Example: launch the player upward

{
  "type": "neoorigins:active_ability",
  "cooldown_ticks": 80,
  "entity_action": {
    "type": "neoorigins:add_velocity",
    "y": 2.0
  },
  "name": "Leap",
  "description": "Launches the player upward."
}

Example: cooldown driven by a counter. Declare a hidden neoorigins:variable counter elsewhere in the origin (say myorigin:dash_cooldown, start: 100), then point the ability at it. Other powers can shorten or lengthen the reuse delay by writing to that counter, e.g. a passive that runs set_resource myorigin:dash_cooldown 40 while sprinting, or a change_resource that adds 20 ticks per consecutive use:

{
  "type": "neoorigins:active_ability",
  "cooldown_resource": "myorigin:dash_cooldown",
  "entity_action": {
    "type": "neoorigins:add_velocity",
    "x": 3.0
  },
  "name": "Adaptive Dash",
  "description": "Dash whose cooldown follows the dash_cooldown counter."
}

The counter’s value is read live on every activation, so the same key can be tuned at runtime by any action. Because counters share the resource keyspace and are declared at power-load time, the cooldown reads correctly even on the very first use (it falls back to the counter’s start).

Legacy active types (active_teleport, active_dash, etc.) remain registered during the deprecation window. The migrateLegacyPowers gradle task can rewrite pack JSON to this type; LegacyPowerTypeAliases covers unmigrated JSON once per-type field remappers are landed.

---

neoorigins:ground_slam

Active AoE slam: damages and knocks back every living entity in a box of radius around the player, including allies and pets. If nothing is in range, no cooldown is spent.

Field	Type	Required	Default	Description
damage	float	no	6.0	Damage dealt to each entity
knockback_strength	float	no	1.5	Radial knockback strength
radius	double	no	6.0	Effect radius in blocks
cooldown_ticks	int	no	120	Cooldown after each use

Example:

{
  "type": "neoorigins:ground_slam",
  "damage": 6.0,
  "radius": 6.0,
  "cooldown_ticks": 120,
  "name": "Tectonic Slam",
  "description": "Crushes nearby enemies with a shockwave."
}

---

neoorigins:tidal_wave

Cone-shaped water blast in the player’s look direction. Knocks back and damages entities caught in the wave.

Field	Type	Required	Default	Description
damage	float	no	4.0	Damage per hit
knockback_strength	float	no	2.0	Forward knockback strength
range	double	no	8.0	Maximum wave distance
cone_angle	double	no	60.0	Total cone angle in degrees (30° to each side of look axis)
cooldown_ticks	int	no	100	Cooldown after each use
hunger_cost	int	no	0	Food points removed per use

Example:

{
  "type": "neoorigins:tidal_wave",
  "damage": 4.0,
  "range": 8.0,
  "cone_angle": 60.0,
  "cooldown_ticks": 100,
  "name": "Tidal Wave",
  "description": "Blasts enemies with a cone of water."
}

---

neoorigins:summon_minion

Active power that summons a mob near the player. Summoned mobs are tracked with caps, despawn timers, and death-damage feedback. Equipment can be configured per slot; all equipment drop chances are zeroed so summoned mobs never drop loot.

Field	Type	Required	Default	Description
mob_type	Identifier	yes	—	Entity type to summon, e.g. minecraft:zombie
max_count	int	no	3	Maximum concurrent minions per player per mob_type
quantity	int	no	1	Minions summoned per activation, capped by remaining max_count headroom
cooldown_ticks	int	no	200	Cooldown after each summon
hunger_cost	int	no	4	Food points consumed per summon
despawn_ticks	int	no	18000	Lifespan after spawn (15 min default)
death_damage	float	no	1.0	Damage taken by the owner when a minion dies
head / chest / legs / feet / mainhand / offhand	Identifier or object	no	(none or iron helmet for head)	Equipment per slot. Either a bare item id ("minecraft:iron_sword") or an object {"item": "...", "enchantments": [{"id": "...", "level": N}]} to enchant the piece
mount	Identifier	no	—	Entity type of an optional mount; each minion rides its own copy (e.g. a piglin riding a hoglin)
attributes	object[]	no	[]	Attribute modifiers applied to each summoned mob at spawn. Each entry is {"attribute": "...", "amount": N, "operation": "..."}

If head is unset, the minion gets an iron helmet by default (sun protection for undead). All drop chances are set to 0.

Multiple minions: set quantity to summon several per activation (still capped by max_count). Hunger is charged once per activation regardless of how many spawn.

Enchanted equipment: any equipment slot accepts the object form {"item": "...", "enchantments": [...]} in place of a bare item id. Each enchantment entry is {"id": "minecraft:sharpness", "level": 3} (level defaults to 1). Unknown enchantment ids are skipped silently. The string form is unchanged, so existing configs keep working.

Attribute modifiers: attributes is a list of modifiers applied to every summoned mob. Each entry takes attribute (e.g. minecraft:generic.max_health, minecraft:generic.attack_damage, minecraft:generic.movement_speed), a numeric amount, and an operation of add_value (flat), add_multiplied_base, or add_multiplied_total (default add_value). Attribute ids resolve with generic./player. prefix tolerance, so the same JSON is portable across the 1.21.1 and 26.1 builds. A raised max_health spawns the mob at full HP.

Mounts: when mount is set, every summoned minion is seated on a freshly spawned copy of that entity using a forced ride, so cross-type stacks like a piglin on a hoglin work. The mount is tracked alongside its rider: it counts against the same mob_type cap, drops no loot, and despawns with the rider.

Brain-driven mobs (piglins, hoglins): these decide aggression through the Brain/memory system rather than goal selectors, so vanilla checks like “the player isn’t wearing gold” would otherwise make a summoned piglin turn hostile. Summoned brain mobs are pacified at spawn and re-pacified every tick: their attack-target/anger memories toward the owner are cleared and piglins are made immune to zombification, so they stay loyal to their summoner.

Example: zombie minion with sword

{
  "type": "neoorigins:summon_minion",
  "mob_type": "minecraft:zombie",
  "max_count": 3,
  "cooldown_ticks": 200,
  "hunger_cost": 4,
  "mainhand": "minecraft:iron_sword",
  "name": "Raise Dead",

neoorigins:tame_mob

Active power that tames a hostile mob the player is looking at. The mob’s AI is rewritten to follow the player, target whatever recently hurt the owner, and join the owner’s own attacks. Tamed mobs are tracked via MinionTracker.

Field	Type	Required	Default	Description
range	double	no	16.0	Max raycast distance to a target
max_tamed	int	no	4	Maximum concurrently-tamed mobs per player
cooldown_ticks	int	no	200	Cooldown after each use
hunger_cost	int	no	3	Food points consumed per tame
despawn_ticks	int	no	36000	Lifespan of each tamed mob (30 min default)
death_damage	float	no	0.5	Damage taken by owner when a tamed mob dies
hostile_only	bool	no	true	If true, only hostile mobs (implementing Enemy) can be tamed, the Monster Tamer default. Set to false to allow taming any non-player Mob (animals, golems, villagers, etc.).
entity_blacklist	string[]	no	[]	Entity ids ("minecraft:warden") and tag refs ("#mymod:untameable") this power can never tame. Checked on top of the built-in boss exclusion.
targeting	string	no	"raycast"	"raycast" tames the single mob you are looking at; "area" tames every eligible mob within range, nearest-first, up to the remaining max_tamed slots. Case-insensitive; anything else falls back to raycast.
entity_whitelist	string[]	no	[]	Area mode only. Entity ids ("minecraft:zombie") and tag refs ("#mymod:tameable") the sweep is restricted to. Empty (default) = any mob (still subject to hostile_only and the blacklists). Ignored in raycast mode.
resource_cost	string	no	""	Optional neoorigins:resource power id spent per mob tamed. Empty = no resource cost (falls back to hunger_cost). When resource bars are globally disabled this amount is charged as hunger instead.
resource_cost_amount	int	no	0	Amount of the resource_cost resource spent per mob tamed.

Targeting modes and per-mob cost

With the default targeting: "raycast" the power tames the one mob under the player’s crosshair, showing the existing per-failure actionbar messages (not_hostile / boss / blacklisted / no_target).

Set targeting: "area" to tame every eligible mob inside range in one activation. Candidates are gathered nearest-first and capped at the remaining max_tamed slots; hostile_only, entity_blacklist, the boss-tier set and the global config blacklist all still apply, and entity_whitelist (if non-empty) further restricts which mobs qualify. A successful multi-tame shows “Tamed N mobs!”.

Cost is charged once per mob tamed, not once per activation. When resource_cost/resource_cost_amount are set and resource bars are enabled, each tame spends that much of the named resource; otherwise it spends hunger_cost food points (or, when a resource is configured but resource bars are globally disabled, resource_cost_amount food points). Taming is greedy: it tames mobs one at a time until either the slots run out or the player can no longer afford one more, then stops. If candidates existed but none could be afforded, it shows “Not enough power to tame!” and consumes no cooldown.

Target must be a non-player Mob. With the default hostile_only: true, only mobs implementing Enemy qualify (villagers, animals, and passive mobs won’t tame); set hostile_only: false to drop that restriction. Boss-tier mobs (the Warden, Ender Dragon and Wither) are always rejected, as is anything that fails the canUsePortal boss check; entity_blacklist lets a pack extend that exclusion to arbitrary mobs, and server operators can do the same for all taming and scare powers at once via the tame_scare_entity_blacklist config list (see Global taming/scare exclusions). A blocked tame shows the “That creature cannot be tamed!” actionbar message (“Cannot tame boss mobs!” for a boss).

Persistence

Tamed mobs behave like vanilla pets: the tame is stored on the mob itself (owner, despawn duration and death-damage ride the entity’s saved data), so it survives everything short of the mob dying or despawn_ticks running out. Concretely:

• Tamer dies: pets survive and are recalled to the tamer when they respawn, crossing dimensions if needed.
• Tamer logs out: pets stay in the world, idle and non-hostile, and resume following/defending the moment the tamer logs back in. No re-tame needed.
• Server restarts / chunk unloads: the pet’s loyalty AI is rebuilt automatically whenever its chunk loads again.

The max_tamed cap and death-damage backlash stay correct across all of the above. Losing the taming power (an origin change) discards the player’s loaded pets outright; that is the one way to revoke a tame. Summoned minions (summon_minion) deliberately do NOT get this treatment: they remain session-bound and vanish with their summoner’s death or logout.

Example (blacklist):

{
  "type": "neoorigins:tame_mob",
  "entity_blacklist": ["minecraft:elder_guardian", "#mymod:untameable"]
}

Example:

{
  "type": "neoorigins:tame_mob",
  "range": 16.0,
  "max_tamed": 4,
  "cooldown_ticks": 200,
  "name": "Beastmaster",
  "description": "Tames hostile mobs to your will."
}

Global taming/scare exclusions

All taming and scare powers (tame_mob, scare_entities and mobs_ignore_player) share one exclusion rule. An entity is excluded when any of these hold:

1. Boss-tier: the Warden, Ender Dragon and Wither. Hardcoded; cannot be overridden.
2. Global config blacklist: the tame_scare_entity_blacklist list in the [entity_exclusions] section of config/neoorigins/admin.toml. Lets a server or pack operator extend the exclusion to arbitrary mobs across every taming and scare power at once:

[entity_exclusions]
    # Entity ids and #tags that can never be tamed, scared,
    # or made to ignore a player by any power. Default: []
    tame_scare_entity_blacklist = ["minecraft:elder_guardian", "#mymod:untouchable"]

1. Per-power entity_blacklist: the optional JSON field on the individual power.

Excluded entities can’t be tamed (tame_mob shows its actionbar message) and aren’t affected by scare_entities or mobs_ignore_player (silently skipped; they flee or target the player exactly as vanilla dictates).

neoorigins:command_pack

Active power that commands every tamed mob (via tame_mob) to attack the entity the player is looking at.

Field	Type	Required	Default	Description
range	double	no	32.0	Max raycast distance to the target
cooldown_ticks	int	no	40	Cooldown after each use

Example:

{
  "type": "neoorigins:command_pack",
  "range": 32.0,
  "cooldown_ticks": 40,
  "name": "Sic 'Em",
  "description": "Orders your pack to attack your target."
}

---

neoorigins:horde_regen

Passively regenerates health on all tamed mobs (via tame_mob) on an interval. Healing only applies when the mob hasn’t taken damage recently.

Field	Type	Required	Default	Description
heal_amount	float	no	1.0	HP restored per interval
interval_ticks	int	no	120	Ticks between heal pulses
combat_cooldown_ticks	int	no	100	Minimum ticks since the mob was last hurt by another mob before it heals. Other damage (fire, falls, players) does not pause healing.

Example:

{
  "type": "neoorigins:horde_regen",
  "heal_amount": 1.0,
  "interval_ticks": 120,
  "name": "Pack Mender",
  "description": "Your tamed mobs regenerate out of combat."
}

---

neoorigins:mount

Active keybind power that raycasts for the living entity in front of the player and seats the player on it. Press the skill key with a target in range to mount; press again while riding to dismount. Mobs are mounted immediately; player targets require consent according to the server’s configured consent mode (MountConsentManager). Boss mobs and already-ridden entities are rejected, and the rider is dismounted automatically if the power is revoked. Good for tamer/druid origins that ride mobs (or other players) on demand.

Field	Type	Required	Default	Description
range	double	no	5.0	Max distance in blocks to raycast for the entity to mount.
cooldown_ticks	int	no	100	Ticks before the key works again (100 = 5s). Dismounting also starts it, and while it runs the key cannot dismount either.
hunger_cost	int	no	0	Hunger consumed per key press that does something: mounting, dismounting, or sending a player-mount request.
allow_players	bool	no	true	Whether this power can mount other players (subject to consent).
allow_mobs	bool	no	true	Whether this power can mount mobs.
block_bosses	bool	no	true	Prevent mounting boss mobs like the Ender Dragon or Wither.
mount_position	enum	no	centered	Where the rider sits: centered (on top) or shoulder (offset to one side).

Example:

{
  "type": "neoorigins:mount",
  "range": 6.0,
  "cooldown_ticks": 60,
  "allow_players": false,
  "mount_position": "shoulder",
  "name": "Mount Beast",
  "description": "Leap onto the creature you're looking at."
}

---

neoorigins:mob_behavior

Rewrites a mob origin’s AI so the mob hunts players (or another entity type). Unlike the player-facing tame/mount powers, this is applied to a mob origin and controls how that mob acquires and holds targets. On grant, a vanilla NearestAttackableTargetGoal (and, when retaliate is set, a HurtByTargetGoal) is added to the mob’s target selector; both are stripped again on revoke, leaving the rest of the mob’s vanilla AI intact. With aggression: "conditional" it behaves piglin-style: the mob only turns hostile toward a player while every hostile_when condition holds (the conditions are evaluated against the prospective player target, not the mob).

Field	Type	Required	Default	Description
aggression	enum	no	neutral	neutral = vanilla AI unchanged (only retaliate applies); hostile = always target the target type on sight; conditional = target a player only while every hostile_when condition holds.
hostile_when	array	no	[]	Conditions (AND-ed) tested against the prospective player target (e.g. “player not wearing gold”), not the mob. Only used when aggression: "conditional"; an empty list behaves like hostile.
retaliate	bool	no	true	Also fight back against whatever damaged the mob (vanilla hurt-by-target).
anger_linger_ticks	int	no	200	Keep the target this many ticks after the trigger stops holding, so the mob calms down gradually (200 = 10s).
aggro_range	double	no	16.0	Max distance to acquire a target.
target_type	resource id	no	players	Entity type id to be hostile toward; omitted = players. Conditions only apply to player targets.
call_for_help	bool	no	false	When retaliating, alert nearby same-type mobs (vanilla pack aggro).

Example: hostile to players only in daylight while not sneaking

{
  "type": "neoorigins:mob_behavior",
  "aggression": "conditional",
  "aggro_range": 24.0,
  "anger_linger_ticks": 300,
  "call_for_help": true,
  "hostile_when": [
    { "type": "neoorigins:exposed_to_sun" },
    { "type": "neoorigins:not", "condition": { "type": "neoorigins:sneaking" } }
  ]
}

---

neoorigins:exhaustion_filter

Meant to filter out specific vanilla exhaustion sources. It currently has no effect: the power loads, but nothing reads it. Imported origins-classes:no_sprint_exhaustion / no_mining_exhaustion translate onto this type, so they do nothing either. For sprint hunger use prevent_action with sprint_food, or action_on_event with mod_exhaustion.

Field	Type	Required	Default	Description
sources	list of string	no	["sprint"]	Exhaustion sources to cancel, e.g. sprint, mining

Example:

{
  "type": "neoorigins:exhaustion_filter",
  "sources": ["sprint"],
  "name": "Tireless",
  "description": "Sprinting no longer drains hunger."
}

---

neoorigins:twin_breeding

On vanilla breeding, spawns a second baby with the configured probability. Only the player credited with the breeding triggers it.

Field	Type	Required	Default	Description
chance	float	no	1.0	Probability (0.0–1.0) of spawning a twin

Example:

{
  "type": "neoorigins:twin_breeding",
  "chance": 0.5,
  "name": "Shepherd",
  "description": "Animals bred near you sometimes produce twins."
}

---

neoorigins:less_item_use_slowdown

Reduces movement slowdown while using items (bow, shield, etc.). Applies a transient generic.movement_speed modifier while isUsingItem() is true and the held item matches.

Field	Type	Required	Default	Description
item_type	string	no	any	any, bow, shield, or any substring matched against the held item’s ID
speed_multiplier	float	no	0.5	ADD_MULTIPLIED_BASE value: 0.5 = +50% walk speed while using

Example: full-speed archery

{
  "type": "neoorigins:less_item_use_slowdown",
  "item_type": "bow",
  "speed_multiplier": 0.8,
  "name": "Strider Archer",
  "description": "Barely slowed while drawing a bow."
}

---

neoorigins:prevent_item_damage

Stops items from losing durability while the holder has the power. Unlike handing out an unbreakable item at spawn, this is a trait of the origin: any matching tool, weapon, or armor the player uses simply never takes durability damage. Implemented via a ItemStack.hurtAndBreak mixin, so it covers every durability path (mining, attacking, blocking, casting).

Field	Type	Required	Default	Description
items	array	no	[]	Item ids or #tags spared from durability loss. Empty list (default) protects every damageable item the holder uses.

Example: unbreaking everything

{
  "type": "neoorigins:prevent_item_damage",
  "name": "Tireless Hands",
  "description": "Your gear never wears down."
}

Example: only tools and bows

{
  "type": "neoorigins:prevent_item_damage",
  "items": ["#minecraft:pickaxes", "#minecraft:axes", "minecraft:bow"],
  "name": "Curator",
  "description": "Your tools and bow never break."
}

---

neoorigins:attract_mobs

Pulls nearby mobs toward the holder each tick, as though the player were holding the mob’s favourite food. Drawn mobs simply path to the player; they are not tamed and do not turn hostile. With no entity_types filter only animals (the vanilla follows-food set) are pulled; supplying ids/tags widens or replaces that to any matching pathfinding mob. Bosses and the tame_scare_entity_blacklist config list are always excluded. Mobs re-path every 10 ticks.

Field	Type	Required	Default	Description
radius	number	no	8.0	Blocks around the holder within which mobs are pulled in
speed	number	no	1.0	Movement-speed multiplier mobs path toward the holder at
entity_types	array	no	[]	Entity ids or #tags drawn in; empty (default) pulls only animals
entity_blacklist	array	no	[]	Entity ids or #tags excluded from attraction even when entity_types (or the animal default) would select them

Example: pied piper of animals

{
  "type": "neoorigins:attract_mobs",
  "radius": 12,
  "name": "Beast Whisperer",
  "description": "Nearby animals follow you as if you held their favourite food."
}

---

neoorigins:no_projectile_divergence

Removes projectile divergence (perfect accuracy) for projectiles shot by the player. Every projectile the player owns is re-aimed along the look direction at its original speed when it spawns, so multishot volleys collapse into one line and projectiles fired by other powers are redirected too. Handled via EntityJoinLevelEvent.

No fields beyond name / description.

Example:

{
  "type": "neoorigins:no_projectile_divergence",
  "name": "Dead Eye",
  "description": "Arrows and projectiles fly true."
}

---

neoorigins:quality_equipment

Equipment the player crafts or upgrades at a smithing table receives bonus attributes. Tools mine faster, weapons hit harder, armor is tougher, and everything lasts longer.

Field	Type	Required	Default	Description
bonus_mining_speed	double	no	0.25	ADD_MULTIPLIED_BASE modifier on mining_efficiency. That attribute’s base is 0, so this only scales the bonus an Efficiency enchantment adds.
bonus_attack_damage	double	no	0.20	Attack damage multiplier for weapons (+20%)
bonus_armor_toughness	double	no	1.0	Flat armor toughness bonus for armor pieces
durability_multiplier	double	no	0.10	Max durability increase for all damageable items (+10%)
intercept_menus	array	no	[]	Extra menu-type ids whose result slot also grants the buff when the finished item is taken.

Working with modded workstations: the buff normally rides the vanilla crafting and smithing paths. intercept_menus opts additional container screens in by menu-type id, so an item taken out of, say, a mod’s own smithing anvil is buffed the same way:

"intercept_menus": [
  "overgeared:smithing_anvil_menu",
  "overgeared:stone_smithing_anvil_menu"
]

Ids that no loaded mod registers simply never match, so listing a menu from a mod the player does not have is harmless: no required_mods guard is needed just for this field.

What gets buffed:

• Tools (pickaxe, axe, shovel, hoe, shears): +mining speed via MINING_EFFICIENCY attribute
• Weapons (sword, axe, trident): +attack damage via ATTACK_DAMAGE attribute
• Armor (helmet, chest, legs, boots): +armor toughness via ARMOR_TOUGHNESS attribute
• All damageable items: +max durability via MAX_DAMAGE component

Example:

{
  "type": "neoorigins:quality_equipment",
  "name": "Quality Craftsmanship",
  "description": "Tools mine faster, weapons hit harder, armor is tougher, and everything lasts longer."
}

Bonuses are applied when the item is taken from a crafting or smithing result (or an intercept_menus result slot) via attribute modifiers stored on the item; smelting does not apply them. Items already carrying the quality modifier are not double-buffed.

Smithing-table upgrades are part of the buffed surface: when a quality item is upgraded (e.g. diamond → netherite), the attribute snapshot is rebuilt from the upgraded item’s own base stats and the durability bonus is recomputed against the upgraded item’s base durability, so the bonus scales with the new material instead of carrying the old item’s stale values.

---

neoorigins:more_smoker_xp

When the player takes cooked food out of a furnace or smoker, they gain round(multiplier) extra nutrition and multiplier × 0.25 extra saturation. It fires on taking the result, so output pulled by a hopper gives nothing. No XP is granted, despite the name.

Field	Type	Required	Default	Description
multiplier	float	no	2.0	Nutrition/saturation bonus multiplier

---

neoorigins:trade_availability

Periodically resets villager trade uses for every villager within a radius of the player.

Field	Type	Required	Default	Description
scan_interval	int	no	40	Ticks between scans
radius	double	no	8.0	Scan radius in blocks

Example:

{
  "type": "neoorigins:trade_availability",
  "scan_interval": 40,
  "radius": 8.0,
  "name": "Charismatic",
  "description": "Villagers near you reset their trades."
}

---

neoorigins:rare_wandering_loot

When a holder right-clicks a wandering trader, that trader gains extra offers (master-tier villager trades and, by chance, a rare treasure trade). This happens once per trader and player; the added offers are then visible to anyone who trades with that trader.

Field	Type	Required	Default	Description
master_slots	int	no	3	Random master-tier villager trades added to wandering traders.
treasure_chance	double (0.0–1.0)	no	0.25	Probability a rare treasure trade is also offered.

Example:

{
  "type": "neoorigins:rare_wandering_loot",
  "name": "Curio Magnet",
  "description": "Wandering traders bring rarer wares while you're around."
}

---

neoorigins:sneaky

Reduces mob detection range: any mob only targets the player when closer than its follow range times detection_multiplier (the lowest one wins if several powers apply). A mob that is already chasing keeps chasing. Handled via LivingChangeTargetEvent.

Field	Type	Required	Default	Description
detection_multiplier	double	no	0.3	Detection range multiplier (0.3 = mobs see you at 30% of their normal range)

Example:

{
  "type": "neoorigins:sneaky",
  "detection_multiplier": 0.3,
  "name": "Shadow Tread",
  "description": "Mobs notice you from much closer than usual."
}

---

neoorigins:muffle_sound

Suppresses the game-event vibrations the player emits, so sculk sensors, calibrated sculk sensors and wardens stop detecting their footsteps, item use, block interactions and the like. Handled via NeoForge’s cancelable VanillaGameEvent: when the cause is a player holding this power, the emission is canceled before any GameEventListener (sculk / warden) receives it.

Field	Type	Required	Default	Description
strength	double	no	1.0	Fraction (0.0-1.0) of emitted vibrations suppressed. 1.0 = fully silent; 0.0 = no muffling; 0.5 = roughly half the player’s vibrations are dropped.

Example:

{
  "type": "neoorigins:muffle_sound",
  "strength": 1.0,
  "name": "Silent Step",
  "description": "Sculk sensors and the Warden can no longer hear you."
}

---

neoorigins:stealth

After sneaking continuously for a threshold number of ticks, the player gains Invisibility, renewed every tick for as long as they keep sneaking. The effect is two seconds long and is not removed when they stand up, so it runs out within two seconds of sneaking stopping. While the holder has Invisibility from any source, mobs cannot pick them as a target. Toggleable off via keybind.

Field	Type	Required	Default	Description
activation_ticks	int	no	200	Sneak time required before invisibility kicks in (10 s default)

Example:

{
  "type": "neoorigins:stealth",
  "activation_ticks": 100,
  "name": "Vanish",
  "description": "Sneak for 5 seconds to turn invisible."
}

---

neoorigins:tree_felling

When the player breaks a log, all connected logs above it are broken too (the search never goes downward). Skipped while sneaking so pack authors can still harvest single logs. Handled via BlockEvent.BreakEvent.

Field	Type	Required	Default	Description
max_blocks	int	no	64	Maximum connected logs to break per activation, not counting the log you chopped. Values below 64 have no effect: the limit is never lower than 64.

Example:

{
  "type": "neoorigins:tree_felling",
  "max_blocks": 64,
  "name": "Arboreal Sense",
  "description": "Fells an entire tree when you chop its base. Sneak to break single logs."
}

---

neoorigins:ultimine

Grants FTB Ultimine vein-mining to the holder. Soft dependency on ftbultimine: when that mod is absent this power is an inert marker and does nothing.

When FTB Ultimine is installed, NeoOrigins registers a restriction handler that permits vein-mining only for players with an active neoorigins:ultimine power and denies it for everyone else. Because FTB Ultimine treats restriction handlers as an AND-gate (the first handler that disallows wins), adding this power to any origin turns vein-mining into an origin-gated ability: only that origin’s holders may ultimine.

The integration is completely dormant unless a loaded pack defines a neoorigins:ultimine power. While no pack uses it, FTB Ultimine behaves exactly as vanilla (the AND-gate handler stays out of the way for everyone). Once at least one ultimine power is loaded, vein-mining is restricted to players who hold an ultimine power. This keeps the soft dependency truly opt-in: installing both mods together changes nothing until a pack adds the power.

This power carries no config. FTB Ultimine’s restriction hook is a coarse allow/deny permission check with no setter for the per-player block limit, the require-tool toggle, or the mining shape, so those are not exposed here. The block count, tool requirement, cooldown, exhaustion/XP cost, and shape all follow FTB Ultimine’s own server config (and any FTB Ranks / attribute overrides). Modeling fields the API cannot honour would be misleading, so the power is deliberately config-light: “while this power is active you may vein-mine.”

Example:

{
  "type": "neoorigins:ultimine",
  "name": "Excavator",
  "description": "Hold the ultimine key and break a block to vein-mine the whole vein. Limits follow the server's FTB Ultimine config."
}

---

neoorigins:craft_amount_bonus

Grants bonus items when crafting a specific output (e.g., more planks per log). Hooks PlayerEvent.ItemCraftedEvent directly, so bonuses only trigger on genuine crafting operations.

Field	Type	Required	Default	Description
output_item	Identifier or #tag	no	minecraft:oak_planks	Item or item tag to watch for; the bonus copies whatever was crafted
bonus_count	int	no	4	Extra copies granted on every craft: exactly this many, with no roll or cap. Copies that do not fit are lost.

Example: quadruple planks from logs

{
  "type": "neoorigins:craft_amount_bonus",
  "output_item": "minecraft:oak_planks",
  "bonus_count": 4,
  "name": "Lumberwright",
  "description": "Gets extra planks when crafting from logs."
}

The bonus fires once per craft event; shift-clicking triggers one event per output stack.

---

neoorigins:tamed_animal_boost

Boosts stats (max health, movement speed) on every tamed animal owned by the player within a radius. Every 60 ticks it adds permanent attribute modifiers with fixed ids (saved on the animal) and heals the animal to full the first time. Revoking the power only strips animals inside the radius at that moment.

Field	Type	Required	Default	Description
health_bonus	float	no	4.0	ADD_VALUE bonus on max health
speed_bonus	float	no	0.1	ADD_VALUE bonus on movement speed
radius	double	no	32.0	Scan radius

Example:

{
  "type": "neoorigins:tamed_animal_boost",
  "health_bonus": 4.0,
  "speed_bonus": 0.1,
  "radius": 32.0,
  "name": "Kinship",
  "description": "Your tamed animals are hardier and faster."
}

---

neoorigins:tamed_potion_diffusal

When the player receives a positive mob effect, it’s also applied to nearby tamed animals owned by the player. Handled via MobEffectEvent.Added.

Field	Type	Required	Default	Description
radius	double	no	16.0	Scan radius for nearby tamed animals

Example:

{
  "type": "neoorigins:tamed_potion_diffusal",
  "radius": 16.0,
  "name": "Shared Fortitude",
  "description": "Positive potion effects also buff your tamed animals."
}

---

Pack-author patterns

Recipes that compose existing power types to cover use cases the built-in types don’t expose directly. Most rely on the Apoli compat surface (neoorigins:-prefixed types handled by OriginsCompatPowerLoader).

Periodic feed / heal via neoorigins:action_over_time

NeoOrigins’ built-in neoorigins:tick_action ships no behaviour at all: it dispatches nothing. For any periodic action (periodically restore hunger, heal a fixed amount, apply an effect, run an arbitrary entity-action), use neoorigins:action_over_time. It is an alias for neoorigins:condition_passive (identical fields), so an optional condition gates whether the action runs each interval.

Periodic hunger restoration (e.g. for an origin that doesn’t eat conventionally):

{
  "type": "neoorigins:action_over_time",
  "interval": 40,
  "entity_action": {
    "type": "neoorigins:feed",
    "food": 1,
    "saturation": 0.2
  }
}

Periodic healing (independent of food / natural_regen_modifier):

{
  "type": "neoorigins:action_over_time",
  "interval": 60,
  "entity_action": {
    "type": "neoorigins:heal",
    "amount": 0.5
  }
}

interval is in ticks (20 = 1 second). The entity_action runs against the player. An optional condition (any ConditionParser verb, e.g. neoorigins:exposed_to_sun) gates each run. Any verb supported by ActionParser works (neoorigins:apply_effect, neoorigins:damage, neoorigins:execute_command, neoorigins:if_else for conditional wrapping, etc.).

neoorigins:cobweb_affinity

Spider-like mobility through cobwebs. Emits the cobweb_affinity capability tag; EntityMakeStuckInBlockMixin reads it to suppress the usual slowdown inside cobwebs, and MovementPowerEvents.onBreakSpeed reads it to multiply cobweb break speed by 10×.

Field	Type	Required	Default	Description
(no fields)	—	—	—	Marker power.

Example:

{
  "type": "neoorigins:cobweb_affinity",
  "name": "Spider Affinity",
  "description": "Move and break cobwebs easily."
}

---

neoorigins:hide_hud_bar

Hides a HUD bar while the power is active. Emits hide_hunger_bar or hide_air_bar capability tags; GuiHudBarsMixin reads them to cancel the matching render call. Governed by the hide_hud_bars client config ([hud] in config/neoorigins/client.toml, default true), so each player decides; if they disable it, the power still applies but their HUD still renders the bar.

Field	Type	Required	Default	Description
bar	string	no	"hunger"	Which bar to hide. "hunger" / "food" hide the hunger bar; "air" / "oxygen" / "breath" hide the air bar. Any other value is a no-op.

Example:

{
  "type": "neoorigins:hide_hud_bar",
  "bar": "air",
  "name": "No Need to Breathe",
  "hidden": true
}

Typically paired with neoorigins:water_breathing or the Automaton pattern so the hidden bar is also being suppressed mechanically; hiding a bar that still ticks is disorienting.

---

neoorigins:particle

Spawns vanilla particles on the player at a fixed cadence. Server-side ServerLevel.sendParticles packetizes to nearby clients, so this works on dedicated servers without a client-side mixin.

Field	Type	Required	Default	Description
particle	string | object	yes	—	Registry id of any SimpleParticleType (e.g. "minecraft:end_rod"). For parameterized particles use the object form: { "type": "minecraft:dust", "color": [1.0, 0.85, 0.2], "scale": 0.6 }
frequency	int	no	8	Emit every N server ticks. Lower = denser.
count	int	no	1	Particles per emission.
spread	[x, y, z] floats	no	[0.25, 0.5, 0.25]	Random offset spread per particle.
offset	[x, y, z] floats	no	[0.0, 1.0, 0.0]	Origin offset from player feet (defaults to ~chest height).
speed	float	no	0.0	Vanilla “speed” parameter: passes through to sendParticles. Most particle types use this as initial-velocity scale; some ignore it.
condition	EntityCondition	no	always-true	Optional gate evaluated each emission tick.

The Origins/Apoli particle power type is auto-translated to this; packs that already use origins:particle, apoli:particle, apace:particle, or apugli:particle work without modification (frequency and particle fields map 1:1).

Example: ambient sparkle aura

{
  "type": "neoorigins:particle",
  "particle": "minecraft:end_rod",
  "frequency": 6,
  "count": 1,
  "spread": [0.4, 0.6, 0.4],
  "name": "Blessed Aura",
  "description": "Faint sparkles trail you wherever you walk."
}

Example: colored gold dust, water-only

{
  "type": "neoorigins:particle",
  "particle": { "type": "minecraft:dust", "color": [1.0, 0.85, 0.2], "scale": 0.6 },
  "frequency": 10,
  "count": 2,
  "condition": { "type": "neoorigins:in_water" },
  "name": "Gilded Wake"
}

Sparkle-aesthetic vanilla particle picks: minecraft:end_rod (cleanest white twinkle), minecraft:firework (bright sparks, heavier), minecraft:enchant (swirling glyphs), minecraft:wax_on (puff burst), minecraft:scrape (copper sparks), minecraft:totem_of_undying (green/gold festive), minecraft:glow (Allay-style soft dots), minecraft:nautilus (subtle blue specs).

---

neoorigins:ender_gaze_immunity

Endermen do not aggro when the player looks at them. Emits the ender_gaze capability tag; EnderManLookMixin reads it and makes the Enderman’s is-looking-at-me check return false.

Field	Type	Required	Default	Description
(no fields)	—	—	—	Marker power.

Example:

{
  "type": "neoorigins:ender_gaze_immunity",
  "name": "Void Gaze",
  "description": "Endermen ignore your gaze."
}

---

neoorigins:xeno_passive

Soft-dependency compat with the Aliens vs Predator mod (avp_alien). Emits the xeno_passive capability tag, which an @Pseudo mixin reads from inside AvP’s AlienPredicates.isHost to short-circuit host eligibility: facehuggers (and the ovomorph hatch-desire / parasite-attachment logic gated off the same predicate) stop treating the holder as a viable host, as if already infected or immune.

This only governs the facehugger host gate. The companion “xenomorphs ignore me entirely” behaviour is delivered separately via a mobs_ignore_player power scoped to the #avp_alien:aliens / #avp_alien:parasites tags. When AvP is not installed the capability simply goes unread and this power is an inert marker.

Field	Type	Required	Default	Description
(no fields)	—	—	—	Marker power.

neoorigins:natural_glide

Grants elytra-style gliding without needing to equip an elytra. Press jump while falling to start fall-flying, exactly as if the player were wearing one.

Emits the natural_glide capability tag. The PlayerStartFallFlyingMixin reads it at the head of Player.tryToStartFallFlying and bypasses the standard chest-slot elytra check, calling startFallFlying() directly.

Field	Type	Required	Default	Description
render_elytra	boolean or string	no	false	When an elytra is drawn on the player’s back: false / "never" (no wings), true / "flying" (only while fall-flying), or "always" (whenever the power is active, folded against the back when not gliding). Flight works either way; this is cosmetic only. Defaults false: this power glides with no visible wings unless you ask for them.
texture_location	identifier	no	vanilla elytra	Custom texture for the drawn elytra, e.g. mymod:textures/entity/my_wings.png. Only applies when render_elytra draws wings at all; the model stays the vanilla elytra (texture swap only). Omit for the vanilla elytra texture.

Example: Phantom spectral wings

{
  "type": "neoorigins:natural_glide",
  "render_elytra": true,
  "name": "Spectral Wings",
  "description": "Glide like an elytra user, no item required. Press jump while falling to spread your wings."
}

Preconditions match vanilla: not on ground, not already fall-flying, not in water, not levitating. Pair with neoorigins:elytra_boost for a full glide + launch-boost kit.

Why wings need asking for. The glide runs with an empty chest slot, and vanilla’s elytra render layer keys off the equipped item, so without render_elytra the player flies with nothing on their back. The field defaults false here rather than true so packs authored against the wingless behaviour keep it, including origins that already supply their own wing model. neoorigins:elytra_flight is the same mechanic with the default flipped on.

The three wing states. render_elytra is a tri-state written as a widened boolean, so the old spellings still mean exactly what they always did:

Value	Wings
false or "never"	Never drawn.
true or "flying"	Drawn only while fall-flying.
"always"	Drawn whenever the power is active, folded against the back when not gliding.

"always" is gated by the power’s own top-level condition like everything else, so it means “whenever the power is active”, not literally always. The string spellings are case-sensitive. Any other value ("Always", "sometimes", the string "true") logs a Failed to parse power config error naming the legal values, and the field falls back to the type’s default (false here and on flight, true on elytra_flight); the power itself still loads. A real equipped elytra still wins in every case: vanilla draws that one and this power stays out of the way.

Contrast with neoorigins:flight: both are pitch-based elytra gliding, but flight is a toggle launched by a mid-air jump, while natural_glide is always available and starts from a fall. For creative-mode hover, see neoorigins:creative_flight.

---

neoorigins:elytra_flight

The native mirror of apoli:elytra_flight: grants elytra-style fall-flight without an equipped elytra, and optionally draws an elytra on the player’s back while gliding.

Flight itself reuses natural glide: this power emits the natural_glide capability, so it drives the exact same activation path (press jump while falling to spread your wings). Everything neoorigins:natural_glide does, elytra_flight does too; it just adds the cosmetic wing render on top.

The wings are purely cosmetic: gliding works the same whether or not an elytra is drawn. When drawn, the model is always the vanilla elytra; texture_location only swaps the texture on that model. If the player is wearing a real equipped elytra, vanilla renders it and this power stays out of the way (no double wings).

Field	Type	Required	Default	Description
render_elytra	boolean or string	no	true	When an elytra is drawn on the player’s back: false / "never" (no wings), true / "flying" (only while fall-flying), or "always" (whenever the power is active, folded against the back when not gliding). Flight works either way; this is cosmetic only.
texture_location	identifier	no	vanilla elytra	Custom texture for the drawn elytra, e.g. mymod:textures/entity/my_wings.png. Only applies when render_elytra draws wings at all; the model stays the vanilla elytra (texture swap only). Omit for the vanilla elytra texture.

Example: spectral wings you can see

{
  "type": "neoorigins:elytra_flight",
  "render_elytra": true,
  "texture_location": "neoorigins:textures/entity/spectral_wings.png",
  "name": "Spectral Wings",
  "description": "Glide like an elytra user — no item required — with shimmering wings on your back."
}

Example: invisible glide (no wings drawn)

{
  "type": "neoorigins:elytra_flight",
  "render_elytra": false,
  "name": "Phantom Drift",
  "description": "Glide with no visible wings."
}

Example: wings that are always on

{
  "type": "neoorigins:elytra_flight",
  "render_elytra": "always",
  "name": "Winged",
  "description": "Your wings are part of you: folded on your back when you walk, spread when you glide."
}

"always" draws the wings whenever the power is active rather than only during a glide; vanilla’s elytra model folds them against the back when the player is not fall-flying, so the standing pose is the usual tucked one. The power’s top-level condition still applies, so “always” means “whenever the power is active”. This is what the built-in Elytrian origin uses: the wings are its body plan, not a flight effect. See the three-state table under neoorigins:natural_glide for the full value list.

If render_elytra is false, this is behaviourally identical to neoorigins:natural_glide. Pair either with neoorigins:elytra_boost for a full glide + launch-boost kit.

---

neoorigins:bare_hand_tool

Makes the player’s empty hand behave like a specific vanilla tool for block-break purposes: tool-tier drop eligibility and break speed both match the configured tool item. Point at any tool item ID and the runtime looks up its tool component to determine which blocks qualify and at what speed.

Emits a capability tag of the form bare_hand_tool:<tool_id> (e.g. bare_hand_tool:minecraft:stone_pickaxe): the tool ID is encoded in the tag so the client-side break-speed predictor and the server-side harvest check can both reach the answer without extra sync state. Wired via BareHandToolEvents on the NeoForge event bus (PlayerEvent.HarvestCheck + PlayerEvent.BreakSpeed). No mixins required.

Field	Type	Required	Default	Description
tool	Identifier	no	minecraft:stone_pickaxe	Any vanilla tool item ID. Determines both break-speed and drop-eligibility.

Example: Caveborn mines like a stone pickaxe with bare hands

{
  "type": "neoorigins:bare_hand_tool",
  "tool": "minecraft:stone_pickaxe",
  "name": "Stone Fists",
  "description": "Bare hands mine like a stone pickaxe — break ores and stone without tools."
}

Only the first active instance applies, so stacking several (e.g. a pickaxe and an axe) does not combine them: the second tool is never consulted.

Only fires when the main hand is empty. Holding any item delegates to vanilla behaviour normally.

---

neoorigins:fortune_when_effect

Applies a virtual Fortune-level drop multiplier whenever a configured MobEffect is active on the player. The vanilla ApplyBonusCount.ORE_DROPS formula is used, giving the same rolling distribution as a real Fortune N pickaxe (count × (max(0, random(level + 2) - 1) + 1)).

Deliberately generic — any origin can emulate an enchantment-like buff by pairing this with any MobEffect (e.g. Caveborn’s Mining Fortune is gated by minecraft:luck granted via eating diamond). Wired via FortuneEffectEvents subscribing to BlockDropsEvent server-side.

Field	Type	Required	Default	Description
effect	Identifier	no	minecraft:luck	The gating MobEffect ID. Bonus only applies while this effect is active on the player.
level	int	no	2	Virtual Fortune level to roll. Higher = more extra drops.
target	string	no	#c:ores	Block tag the bonus applies to. Use #tagname syntax. Defaults to the NeoForge common ores tag; pack authors can narrow to a vanilla sub-tag like #minecraft:diamond_ores or a custom tag.

Vanilla parity: minecraft:ancient_debris is hardcoded-excluded because netherite is the single vanilla ore that ignores Fortune. Every other vanilla ore (iron, gold, copper, coal, diamond, emerald, lapis, redstone, nether_gold, nether_quartz) is covered by #c:ores and will roll the bonus normally.

Example: Caveborn Mining Fortune (gated by Luck from eating diamond)

{
  "type": "neoorigins:fortune_when_effect",
  "effect": "minecraft:luck",
  "level": 2,
  "target": "#c:ores",
  "name": "Mining Fortune",
  "description": "While Luck is active, ore blocks drop as if mined with Fortune II."
}

The held tool is ignored, and the bonus multiplies whatever drops the block produced, so it stacks with a real Fortune enchantment and also applies to an ore block mined with Silk Touch. Stacking isn’t additive: only the first matching power fires per break. Author variants as separate powers with different effect gates rather than expecting them to compound.

---

neoorigins:dodge_chance

Percentage chance to completely dodge incoming damage. When triggered, the damage event is cancelled entirely. Applied via CombatPowerEvents.

Field	Type	Required	Default	Description
chance	float	no	0.15	Dodge probability (0.0–1.0). 0.15 = 15% dodge.

Example:

{
  "type": "neoorigins:dodge_chance",
  "chance": 0.2,
  "name": "Evasion",
  "description": "20% chance to dodge incoming attacks."
}

---

neoorigins:thorns_on_hit

Passive thorns — when the player takes damage from a living attacker (including the owner of a projectile), the attacker takes damage back. Optionally sets the attacker on fire. Applied via CombatPowerEvents.

Field	Type	Required	Default	Description
damage	float	no	2.0	Thorns damage dealt to the attacker.
fire_ticks	int	no	0	Fire ticks applied to the attacker (0 = no fire).

Example:

{
  "type": "neoorigins:thorns_on_hit",
  "damage": 3.0,
  "fire_ticks": 40,
  "name": "Ember Thorns",
  "description": "Melee attackers take 3 damage and catch fire."
}

---

neoorigins:light_level_effect

Applies a status effect when the player is at or below a certain light level. Removes the effect when they move to brighter light, including the same effect from any other source (a potion, a beacon).

Field	Type	Required	Default	Description
max_light_level	int	no	4	Light level threshold (inclusive).
effect	resource location	yes	—	Status effect to apply.
amplifier	int	no	0	Effect amplifier.
ambient	boolean	no	true	Ambient effect flag.
show_particles	boolean	no	false	Show effect particles.
show_icon	boolean	no	false	Show effect icon on HUD.

Example: invisibility in darkness

{
  "type": "neoorigins:light_level_effect",
  "max_light_level": 4,
  "effect": "minecraft:invisibility",
  "name": "Shadow Meld",
  "description": "Become invisible in darkness."
}

---

neoorigins:low_hp_threshold

Applies one or more status effects when the player’s HP drops below a percentage threshold. Effects are removed when HP rises above the threshold, including the same effects from any other source (a potion, a beacon).

Field	Type	Required	Default	Description
threshold	float	no	0.5	HP fraction (0.0–1.0). 0.5 = below 50%.
effects	list of { effect, amplifier }	yes	—	Effects to apply while below threshold.

Example: berserker rage below 25% HP

{
  "type": "neoorigins:low_hp_threshold",
  "threshold": 0.25,
  "effects": [
    { "effect": "minecraft:strength", "amplifier": 1 },
    { "effect": "minecraft:speed", "amplifier": 0 }
  ],
  "name": "Death's Embrace",
  "description": "Gain Strength II and Speed below 25% HP."
}

---

neoorigins:burn

Sets the player on fire at a configurable interval. Used for origins that are perpetually burning or catch fire under certain conditions (pair with a condition on the power JSON to gate on daylight, biome, etc.).

Field	Type	Required	Default	Description
interval	int	no	20	Ticks between fire applications.
burn_duration	int	no	100	Fire duration in ticks per application.

Origins compat: translates origins:burn.

Example: smoulder in sunlight

{
  "type": "neoorigins:burn",
  "interval": 40,
  "burn_duration": 60,
  "condition": { "type": "neoorigins:exposed_to_sun" },
  "name": "Sun Scorch",
  "description": "Burns when exposed to direct sunlight."
}

---

neoorigins:walk_on_fluid

Allows the player to walk on the surface of a fluid (water, lava, or both), using the same vanilla mechanic as Striders (LivingEntity.canStandOnFluid). The player can still dive by jumping into the fluid.

Field	Type	Required	Default	Description
fluid	string	no	both	Which fluid to walk on: water, lava, or both

Example: walk on water

{
  "type": "neoorigins:walk_on_fluid",
  "fluid": "water",
  "name": "Water Walking",
  "description": "Can walk on water surfaces."
}

Origins compat: translates origins:walk_on_fluid.

---

neoorigins:extra_inventory

Gives the player an extra inventory opened via the skill keybind. Uses vanilla’s chest UI, dynamically sized to fit the configured slot count (1-6 rows). Contents are persisted across sessions.

Field	Type	Required	Default	Description
size	int	no	9	Number of slots (rounded up to nearest row of 9, max 54 = 6 rows)
drop_on_death	bool	no	false	Whether to drop contents on death
title	string	no	""	Literal title drawn on the container screen. Blank/absent uses the translatable container.neoorigins.extra_inventory. Plain text, not a JSON text component.

Example: 27-slot extra inventory

{
  "type": "neoorigins:extra_inventory",
  "size": 27,
  "name": "Shulker Inventory",
  "description": "Press your skill key to open an extra inventory."
}

Origins compat: translates origins:inventory / origins:shulker_inventory.

---

neoorigins:ignore_water

Makes the player unaffected by water: full movement speed in water (via water_movement_efficiency attribute) and immune to water-current pushing (via EntityIgnoreWaterMixin). Emits the ignore_water capability tag.

Field	Type	Required	Default	Description
(no fields)	—	—	—	Marker power.

Origins compat: translates origins:ignore_water.

Example:

{
  "type": "neoorigins:ignore_water",
  "name": "Hydrophobic",
  "description": "Water doesn't slow you down or push you around."
}

---

neoorigins:ignore_fluid

Makes the player totally ignore one or more fluids. Where ignore_water only removes water’s speed penalty and current pushing, this power removes the fluid from the player’s world entirely: no buoyancy, no drag, no current push, no drowning, no lava burn, no fog or screen overlay, no swim pose.

It does that by intercepting fluid detection rather than each individual effect. EntityFluidInteractionIgnoreFluidMixin hands back an empty fluid state for ignored fluids inside EntityFluidInteraction.update, the single body scan that feeds buoyancy, drag, current push, isInWater()/isInLava(), lavaHurt(), the swim pose, drowning and the air bar. CameraIgnoreFluidMixin does the same for Camera.getFluidInCamera, which decides fog and the underwater distortion without ever consulting the entity. BlockStateBaseIgnoreFluidMixin cancels entityInside for the fluid’s own block, which is how a mod-authored fluid applies its own damage or effects.

Because every vanilla fluid behaviour reads those same values, they all fall away together, and so do most third-party mods, since they query the same methods.

Field	Type	Required	Default	Description
fluid	string or array	no	—	Fluid to ignore: a fluid id ("minecraft:lava"), a fluid tag ("#c:milk"), or an array of either
fluids	array	no	—	Plural spelling of fluid. Both keys are read and their entries merged

Naming any fluid of a fluid type ignores the whole type, so "minecraft:water" also covers minecraft:flowing_water — that is what makes poured buckets work. Entries without a namespace get minecraft: (so "lava" means "minecraft:lava"). If neither key is given the power defaults to water and lava, so a marker-only entry is never a silent no-op. Unknown or misspelled ids are dropped quietly rather than failing the datapack load: the power simply ignores nothing for that entry.

Emits the ignore_fluid capability tag plus one ignore_fluid:<id> tag per entry, so the client and server agree without any extra sync.

Modded fluids on this version. The field shape is identical across every branch of the mod, so a datapack naming a modded fluid loads and validates here exactly as it does on 1.21.1. Whether its physics are suppressed depends on the NeoForge build. From NeoForge 26.1.2.99, entity fluid tracking is keyed by fluid type, so a modded fluid is tracked and ignored as on 1.21.1. Older 26.1 builds track only fluids in the minecraft:water and minecraft:lava fluid tags; there an entry naming another fluid is accepted and syncs its capability tag but drives nothing on the movement side, though the entityInside guard still cancels the fluid’s own damage or effects.

Not covered. A mod that runs its own level.getFluidState(pos) check per tick — rather than asking the entity whether it is in a fluid — is doing its own detection and cannot be intercepted from here; it will still see the fluid. The same goes for anything keyed off the block state rather than the fluid state (a mod checking state.is(Blocks.LAVA) directly). Fluid rendering is untouched: the fluid is still drawn normally, you simply pass through it as if it were air.

One deliberate side effect: the entityInside guard is keyed on the block’s fluid state, so a waterlogged block’s own entityInside behaviour is suppressed too while you ignore water. In practice that means things like bubble columns stop pushing you, which is the intended reading of “water does not affect me”.

ignore_water is unchanged and still supported; use it when you only want water’s movement penalty gone, and this power when you want the fluid to stop existing for the player.

Example: swim through lava unharmed

{
  "type": "neoorigins:ignore_fluid",
  "fluid": "minecraft:lava",
  "name": "Magma Born",
  "description": "Lava does not slow, push, burn or blind you."
}

Example: ignore several fluids, including a modded one

  "name": "Untouchable",
  "description": "Liquids simply don't register."

---

neoorigins:overlay

Renders a full-screen texture overlay on the player’s HUD. Client-side only: the server emits a capability tag encoding the texture path and strength; VisualEffectsHandler on the client reads it and draws the overlay.

Field	Type	Required	Default	Description
texture	resource location	yes	—	Overlay texture (e.g. "minecraft:textures/misc/pumpkinblur.png").
strength	float	no	1.0	On this version any value above 0 draws at full opacity, and 0 or below draws nothing. Only the first active overlay is drawn.

Origins compat: translates origins:overlay.

Example: dim vignette

{
  "type": "neoorigins:overlay",
  "texture": "minecraft:textures/misc/pumpkinblur.png",
  "strength": 0.3,
  "name": "Tunnel Vision",
  "description": "Your peripheral vision is dimmed."
}

---

neoorigins:model_color

Tints the player model with an RGBA colour.

The tint is drawn on 1.21.1, where the client applies a colour multiply during the player render pass. It is not drawn on 26.1 or 26.2, because those versions removed RenderSystem.setShaderColor and the mod has no replacement pass yet, so nothing paints the model. Everything else about the power is unchanged here: it loads, validates its fields, honours enabled and condition, and syncs its state to the client. A datapack naming this type is not broken on these versions, it simply shows no colour.

Field	Type	Required	Default	Description
red	float	no	1.0	Red channel (0.0–1.0).
green	float	no	1.0	Green channel (0.0–1.0).
blue	float	no	1.0	Blue channel (0.0–1.0).
alpha	float	no	1.0	Alpha channel (0.0–1.0).
condition	object	no	—	EntityCondition that gates when the tint is applied. When absent, the tint is always active. When present, the colour only shows while the condition evaluates true.
enabled	bool	no	true	Kill switch: when false the power stays attached but never tints. Lets a server owner drop one tint from power_overrides.toml without editing the datapack.

When two or more model_color powers are active at once, the blend rule is to average the channels rather than let one win: two tints produce their midpoint, three their mean. That is what 1.21.1 draws; on 26.1 and 26.2 it stands as the defined rule with no render pass to apply it. A conditioned tint is re-evaluated once a second on every version, so the synced state appears and clears as the condition flips rather than only on login or toggle.

Origins compat: translates origins:model_color.

Example: ghostly blue tint

{
  "type": "neoorigins:model_color",
  "red": 0.6,
  "green": 0.7,
  "blue": 1.0,
  "alpha": 0.8,
  "name": "Spectral Hue",
  "description": "Your form shimmers with a faint blue glow."

  "name": "Blood Rage",
  "description": "Your body glows red when near death."
}

---

neoorigins:entity_model

Overrides the player’s rendered model with another entity’s model: a “morph”. The server resolves the power’s config into a single morph description and broadcasts it to every client tracking the player, which renders a cached stand-in entity of that type in place of the player, for both the morphed player (third-person) and everyone who can see them. A morph changes how the player sounds and how big they are as well as how they look.

Field	Type	Required	Default	Description
morph	string	no	—	Named morph definition to use, e.g. neoorigins:sheep. A bare name resolves in the neoorigins namespace. See Morph definitions below.
entity_type	string	no	—	Entity id whose model replaces the player’s, e.g. minecraft:slime. It also supplies the morph’s voice and collision box.
nbt	object	no	—	Partial NBT applied to the stand-in to pick a variant, e.g. {"Color": 14} for a red sheep.
scale	number	no	1.0	Uniform scale of the morph model, and of its collision box along with it.
hitbox	boolean	no	true	Whether the player collides at entity_type’s size instead of their own. See Morph hitbox below.
render_held_item	boolean	no	true	Whether the player’s held items are drawn on the morph, so others can see what they’re carrying. A morph with hands holds the item; one without floats it in front of the body instead.
render_armor	boolean	no	true	Whether the player’s worn armour is drawn on the morph. Only takes effect on morphs whose entity renders armour at all: zombies, skeletons and piglins do; sheep, slimes and villagers do not.
first_person	enum	no	item	What the morphed player sees in their own view: item draws the held item without the vanilla arm, arm also draws the morph’s own arm, hidden draws nothing. See First-person view below.
arm	string	no	—	Name of the bone to draw as the morph’s arm in arm mode. See First-person view below.
skin	object	no	—	Reskin the player instead of replacing their model. See Skin morphs below.
entity_sounds	boolean	no	true	Whether the player borrows the voice of entity_type. See Morph sounds below.
sounds	object	no	—	Explicit sound overrides, layered over that voice. See Morph sounds below.

Every field is optional because a morph can be described two ways: inline, or by referencing a named definition with morph. When both are present the inline fields win, so a pack can reuse a definition and tweak one detail. A power with neither leaves the player looking like themselves.

First-person view

Everyone else sees the morph. The morphed player mostly sees their own hands, and those hands are the one part of the player a morph cannot simply replace: vanilla draws a player arm there, and a slime has no arm to put in its place. first_person picks which of the three honest answers you want:

Value	What the player sees
item	The held item, floating, with no arm behind it. The default: it works for every morph, because it never needs the morph to have an arm.
arm	The morph’s own arm when the hand is empty, and the held item when it isn’t, the same rule vanilla uses for the player’s arm.
hidden	Nothing. Right for a morph that shouldn’t have visible hands at all.

arm is worth setting for humanoid morphs (a zombie, a skeleton, a piglin, a villager) where the arm exists and reads correctly. On a morph with no arm bone it costs nothing: the view falls back to the item behaviour rather than showing something wrong.

The bone is found automatically. Humanoid mobs are recognised outright, and other models are searched for a bone named right_arm or left_arm (and the usual variants: rightArm, arm_right, right_hand, or a plain arm). Set arm only when that picks the wrong bone or finds nothing, and set it to the bone’s name as the model defines it. Nothing stops you naming a bone that isn’t an arm; a morph that should raise a wing or a claw into view is a legitimate use. A name the model doesn’t have logs a warning once and falls back to auto-detection, so a typo shows up in the log rather than silently emptying the view.

The arm is drawn where a player’s arm would be, because that is where the hand belongs on screen. A morph whose arm is much longer or shorter than a player’s will look it: that’s the cost of borrowing another mob’s geometry, and it’s why the default doesn’t do this.

  "type": "neoorigins:entity_model",
  "entity_type": "minecraft:zombie",
  "first_person": "arm"
}

Skin morphs

entity_type replaces the player’s model with a mob’s. skin does something different and often more useful: it keeps the player’s own model and swaps the textures drawn on it. Because the player is still being rendered as a player, arms, animations, armour, held items and first-person view all keep working with nothing extra to configure. Reach for skin for anything humanoid, and entity_type when you actually want a different shape.

Field	Type	Required	Default	Description
texture	string	no	—	Body texture, as an asset id.
cape	string	no	—	Cape texture.
elytra	string	no	—	Elytra texture. Vanilla falls back to the cape texture when unset.
model	enum	no	—	Arm width: slim (three-pixel arms) or wide (four).

Textures are addressed as asset ids, not file paths: neoorigins:morph/fox loads assets/neoorigins/textures/morph/fox.png. The file must be a 64×64 player skin; a mob texture will not map onto the player model.

Every key is layered over the player’s real skin rather than replacing it wholesale, so a skin block that only sets cape leaves the body alone, and one that only sets texture doesn’t strip a player’s real cape. Leaving model unset keeps whatever arm width the player already had, which is what a texture-only reskin normally wants; set it when your texture was drawn for a specific arm width.

  "type": "neoorigins:entity_model",
  "skin": {
    "texture": "neoorigins:morph/frostborn",
    "model": "slim"
  },
  "name": "Frostborn",
  "description": "Your skin pales to frost-bitten blue."
}

Morph sounds

A morph is audible as well as visible. Naming an entity_type also hands the player that mob’s voice: its hurt sound, its death sound, its landing sounds and its swimming sounds. A morphed creeper hisses when it takes a hit; a morphed slime squelches when it lands. Nothing has to be configured for this; it is what entity_type does now.

Set entity_sounds to false to look like the mob and still sound like yourself.

sounds overrides individual sounds on top of that. It is the way to give a voice to a morph that has no entity_type at all (a skin morph), to use a sound your own pack ships, or to change just one of the sounds a mob would otherwise supply.

Field	Type	Required	Default	Description
hurt	string	no	—	Played when the player takes damage.
death	string	no	—	Played once when the player dies.
fall_small	string	no	—	Landing from a short fall (four blocks or less).
fall_big	string	no	—	Landing from a long fall.
swim	string	no	—	Looping sound while swimming.
splash	string	no	—	Entering or leaving water.
splash_high_speed	string	no	—	The faster splash used when hitting water hard.

Every value is a sound event id: minecraft:entity.fox.hurt, not a path to an .ogg. Custom sounds need an entry in your pack’s sounds.json the same as anywhere else. An id that isn’t registered is reported once in the log and then ignored, so a typo costs you one sound rather than silencing the player.

Like skin, each key is layered rather than wholesale: a sounds block that only sets hurt leaves the rest of the mob’s voice alone, and fall_small and fall_big resolve independently of each other.

  "description": "You hiss when struck, and go out with a sound of your own."
}

Two sounds deliberately do not change. Step sounds come from the block underfoot, not from the entity, so morphing into a chicken does not make you sound like one walking. Ambient sounds (a zombie’s groan, a cat’s meow) have no player equivalent to hook, so a morph never idles aloud.

Morph hitbox

A morph is tangible, not just a picture. Naming an entity_type gives the player that mob’s collision box: a small slime fits through a one-block gap, a spider walks under a slab, an iron golem no longer does. Eye height follows the box, so a short morph genuinely sees from lower down and a tall one sees over a fence. scale resizes the box along with the model, so the two never disagree.

The size is read from the morph target with its variant NBT already applied, which means {"Size": 0} on a slime gives you the small slime’s box, not the default one. neoorigins:size_scaling still applies on top, so a scaled-up player morphed into a slime collides as a scaled-up slime.

Set hitbox to false for a look-only morph: the player keeps their own box and eye height, and only the model changes.

{
  "type": "neoorigins:entity_model",
  "entity_type": "minecraft:slime",
  "nbt": { "Size": 0 },
  "name": "Slimeling",
  "description": "Small enough to slip through a gap a person cannot."
}

Growing into a wall. A morph that would make the player bigger than the space they are standing in is held back rather than forced: the player keeps their own size, and the morph takes hold the moment they step somewhere it fits. Nothing is cancelled and nothing teleports. So crouching into a one-block gap as a small slime works, and a power that would grow you back while you are still in that gap simply waits until you are out of it. The same check runs while a morph is already applied, so a player walled in mid-morph shrinks back to their own size instead of suffocating.

A morph target far larger than a player (an ender dragon, a ravager) is not rejected, but in practice it will rarely find room, so expect it to spend most of its time held back. Very large morphs are better authored with hitbox set to false.

Morph definitions

morph refers to a reusable definition: the same entity type, variant NBT and scale used across several origins, written once. The built-ins are slime, magma_cube, sheep, cat, villager, creeper, zombie, skeleton, enderman and spider.

Define your own (or replace a built-in) at data/<ns>/neoorigins/morphs/<name>.json, using the same fields as above minus morph itself:

{
  "entity_type": "minecraft:cat",
  "nbt": { "variant": "minecraft:siamese" },
  "scale": 0.9,
  "first_person": "hidden"
}

A datapack file always overrides the built-in of the same id. An unknown morph id logs a warning once and is ignored, rather than silently rendering nothing.

Notes:

• The hitbox does change, unless you set hitbox to false. See Morph hitbox. It composes with neoorigins:size_scaling rather than fighting it: that power writes the vanilla minecraft:scale attribute, which is applied on top of the morph’s own size.
• Sounds do change, unless you set entity_sounds to false. See Morph sounds.
• Variants come from nbt, so any variant the entity itself reads from save data works with no per-mob support needed: sheep colour, cat and villager types, slime size, and so on. The Team key is ignored — a render stand-in has no business joining a scoreboard team.
• Held items and armour carry over to the morph unless you turn them off. Where the morph’s model draws equipment itself (zombies, skeletons, piglins, anything humanoid), the items go into its real hands and armour slots and animate with it. Where it does not (a slime has no hand bone), the held item floats just above and in front of the body instead. render_armor therefore has no visible effect on a morph whose entity never draws armour.
• Player state carries across. Invisibility, the red damage flash, the freezing/powder-snow overlay, the death topple, and the swing and use animations all mirror the player onto the morph, so a morphed player still reads as hurt, frozen or dying at a glance.
• Nameplate is preserved: the player’s display name still renders above the morph under the same visibility rules vanilla uses.
• An entity type that can’t be rendered (unknown id, no registered renderer, players) is reported once in the log and the player keeps their normal model, rather than turning invisible.

Example: slime morph, using the built-in definition

{
  "type": "neoorigins:entity_model",
  "morph": "slime",
  "name": "Slime Form",
  "description": "You appear as a slime to yourself and others."
}

Example: a big red sheep, defined entirely inline

{
  "type": "neoorigins:entity_model",
  "entity_type": "minecraft:sheep",
  "nbt": { "Color": 14 },
  "scale": 1.4,
  "first_person": "hidden",
  "name": "Ram Form",
  "description": "You take on the shape of a great red ram."
}

neoorigins:bounce_on_land

Reflects the player’s downward impact velocity back upward on landing, mimicking a slime block: a slime-morphed player springs off the ground after a fall. The bounce fires only on the airborne→ground transition, using the impact speed captured the tick before landing (by the landing tick the player’s own velocity has already been collision-clamped to ~0). The new velocity is pushed to the client through the same packet path vanilla uses for server-applied knockback, so the launch feels responsive.

Field	Type	Required	Default	Description
restitution	number	no	0.8	Fraction of downward impact velocity reflected back up on landing; <1 damps each successive bounce so the player settles.
min_velocity	number	no	0.63	Minimum downward speed (blocks/tick) needed to trigger a bounce, so jumps and short drops don’t micro-bounce; 0.63 is the floor a 4-block fall clears and a 3-block fall does not.
max_velocity	number	no	1.6	Cap on the upward launch speed (blocks/tick) so terminal-velocity falls don’t fling the player absurdly high.

Notes:

• Sneaking suppresses the bounce: matching slime-block behavior and giving players a deliberate way to stop bouncing.
• Running speed carries through the bounce. The launch keeps the horizontal speed the player landed with, so landing mid-sprint springs them onward instead of stopping them where they land.
• Pair with neoorigins:prevent_action ("action": "fall_damage") so the impact driving the bounce doesn’t also hurt.

Example: springy slime body

{
  "type": "neoorigins:bounce_on_land",
  "restitution": 0.8,
  "name": "Springy Body",
  "description": "Like a slime, you rebound off the ground after a fall. Hold sneak to stay put."
}

---

neoorigins:become_dragon

Soft-compat hook for the Dragon Survival mod: while the power is granted, the holder is a Dragon Survival dragon of the configured species; revoking it reverts them to human form. The power is a pure hook — Dragon Survival supplies all of the resulting traits, growth, abilities and hunters. The form is re-applied on login and respawn, so it survives relog and death.

Field	Type	Required	Default	Description
species	string	yes	—	Dragon Survival species id, e.g. dragonsurvival:cave_dragon.
stage	string	no	dragonsurvival:newborn	Starting growth stage. Blank or unresolvable ids fall back to the species default.

Notes:

• Inert without Dragon Survival. The power no-ops when the mod is absent. Always pair it (and the origin that grants it) with "required_mods": ["dragonsurvival"] so the content never loads, or appears in the picker, without the target mod. The three built-in dragon origins (Cave, Forest, Sea Dragon) follow this pattern.
• The bridge binds to Dragon Survival’s internals reflectively (the mod exposes no addon API): if a future Dragon Survival release renames those internals, the power logs one warning and stops transforming players rather than crashing. See COMPATIBILITY.md.

Example: cave dragon form

{
  "type": "neoorigins:become_dragon",
  "species": "dragonsurvival:cave_dragon",
  "stage": "dragonsurvival:newborn",
  "required_mods": ["dragonsurvival"],
  "name": "Cave Dragon Form",
  "description": "Take the shape of a cave dragon."
}

---

neoorigins:lava_vision

Increases the player’s vision distance while the camera is submerged in lava by pushing back the lava fog planes. Holders also lose the first-person burning-screen fire overlay: the power is meant for fire-immune origins, where the flame animation is noise. Client-side rendering is handled by VisualEffectsHandler via ViewportEvent.RenderFog and RenderBlockScreenEffectEvent.

The planes can be set two ways. strength scales vanilla’s own values, while start and end replace them outright, in blocks. An absolute field always wins for the plane it names; a plane with no absolute value falls back to the multiplier.

Field	Type	Required	Default	Description
strength	float	no	3.0	Fog distance multiplier (higher = further vision in lava). Ignored for whichever plane start or end sets.
start	float	no	—	Absolute fog start, in blocks: the distance at which fog begins.
end	float	no	—	Absolute fog end, in blocks: effectively how far you can see through lava.

Note that strength is relative to values that vanilla itself varies, so the same multiplier gives different distances depending on status effects: without fire resistance the lava fog runs 0.25 to 1.0 blocks, with it 0.0 to 5.0. Use start/end when you want a distance you can count on. A strength of 0, or an end at or before start, is discarded rather than applied, since collapsing both planes onto each other paints the whole screen a flat fog colour.

Origins compat: origins:lava_vision maps s to start and v to end. Both are absolute distances upstream too, so the common {"s": 0, "v": 15} spelling carries over unchanged and means “see 15 blocks through lava”.

Example:

{
  "type": "neoorigins:lava_vision",
  "strength": 5.0,
  "name": "Magma Sight",
  "description": "See clearly through molten rock."
}

Example: an exact sight distance, independent of fire resistance

{
  "type": "neoorigins:lava_vision",
  "start": 0.0,
  "end": 15.0,
  "name": "Magma Sight",
  "description": "See fifteen blocks through molten rock."
}

---

neoorigins:shader

Meant to apply a post-processing shader to the player’s view. It currently has no visible effect on this version: the power loads, but the client side has not been ported to the new post-processing pipeline, so nothing is drawn.

Field	Type	Required	Default	Description
shader	resource location	yes	—	Shader id (e.g. "minecraft:desaturate", "minecraft:spider").

Origins compat: translates origins:shader.

Example: desaturated phantom view

{
  "type": "neoorigins:shader",
  "shader": "minecraft:desaturate",
  "name": "Phantom Eyes",
  "description": "The world appears washed of colour."
}

---

neoorigins:wraith_phase

Toggleable spectral phasing. When active the player walks through solid blocks horizontally. While inside a solid block, jump and sneak give vertical control (jump = up, shift = down): that movement is velocity, and the power never grants flight. Holding shift on the surface phases downward into the ground. Certain blocks cannot be phased through.

Field	Type	Required	Default	Description
blocked_blocks	list of string	no	["minecraft:obsidian", "minecraft:crying_obsidian", "minecraft:bedrock"]	Blocks that cannot be phased through, each a block id or a block tag written as #namespace:tag. An entry that does not parse is skipped with a warning in the log rather than failing the power.
exhaustion_per_tick	float	no	0.15	Hunger drain per tick while inside solid blocks.
always_on	bool	no	false	When true, the power is passive (always active, no toggle, no skill key slot). Configurable per tier in the mod config.

Emits the wall_phase capability while active (toggled on or always_on).

Example: base wraith phase

{
  "type": "neoorigins:wraith_phase",
  "blocked_blocks": ["minecraft:obsidian", "minecraft:crying_obsidian", "minecraft:bedrock"],
  "exhaustion_per_tick": 0.15
}

Example: apex tier (only bedrock blocks, minimal drain)

{
  "type": "neoorigins:wraith_phase",
  "blocked_blocks": ["minecraft:bedrock"],
  "exhaustion_per_tick": 0.075
}

---

neoorigins:resource

A named, persistent, HUD-visible resource bar. Values are stored per-player and synced to the client for rendering. Supports regeneration with conditions, threshold actions when min/max are hit, and compatibility with the Origins change_resource / resource condition system.

Field	Type	Required	Default	Description
min	int	no	0	Minimum resource value
max	int	no	100	Maximum resource value
start_value	int	no	max	Initial value when granted
regen_rate	int	no	0	Amount regenerated per interval (0 = no regen)
regen_interval	int	no	20	Ticks between regen ticks
regen_condition	EntityCondition	no	always-true	Condition for when regeneration occurs
min_action	EntityAction	no	noop	Action run once each time the value drops to min (not every tick while it stays there)
max_action	EntityAction	no	noop	Action run once each time the value rises to max (not every tick while it stays there)
hud_render	object	no	—	HUD display settings (see below)
hidden	bool	no	false	Whether to hide the bar from the HUD
backing	string	no	""	Optional external pool that backs the bar’s value instead of the internal store. Only irons_spellbooks:mana is supported (see below); when set, min/max are ignored and the bar auto-scales to Iron’s live max mana. Empty = internally stored.

backing: bind the bar to Iron’s Spells mana

Set "backing": "irons_spellbooks:mana" to make the bar’s value read from and write to the player’s Iron’s Spells ‘n Spellbooks mana pool rather than NeoOrigins’ own per-player store. The mana pool stays authoritative:

• Reads (the HUD bar, the resource condition, resource_cost gating) observe the live mana value.
• Writes are additive-only: change_resource adds its change amount (positive to grant, negative to drain), regen_rate adds per interval, and resource_cost deductions subtract. All of these add a delta to the pool; NeoOrigins never overwrites mana absolutely (that would fight Iron’s own regen and casting bookkeeping).
• Absolute sets are ignored. set_resource and change_resource with "operation": "set" are no-ops on a mana-backed bar (logged once). Use additive change_resource instead.
• min/max are optional and ignored: the bar auto-scales. A mana-backed bar uses min = 0 and max = Iron’s live max mana, which is the MAX_MANA attribute (it moves with gear, level, and effects), so you don’t declare a static scale. Iron’s own mana bar reads the same attribute, so the two bars fill identically. Any author min/max on a mana-backed power is accepted but has no effect (they still matter for ordinary, non-backed resources). A drain is floor-clamped so mana never goes below 0.
• The dynamic max is pushed live. Because the max can change mid-game (e.g. a gear swap that grants more max mana), the periodic value sync carries the current max, so the HUD re-scales without waiting for a full re-sync.
• Iron’s Spells is a soft dependency. If it isn’t installed, the bar reads empty and writes do nothing (logged once); it does not fall back to an internal value. Gate the origin/power with "required_mods": ["irons_spellbooks"] if the bar should only exist when Iron’s is present.

Because Iron’s changes mana out from under the game (regen, spellcasting), a mana-backed bar re-syncs its value (and live max) to the client every 10 ticks so the HUD tracks the pool live.

{
  "type": "neoorigins:resource",
  "backing": "irons_spellbooks:mana",
  "hud_render": {
    "label": "Mana",
    "color": "#55AAFF"
  },
  "name": "Arcane Reserve",
  "description": "Your Iron's Spells mana, shown as an origin resource bar."
}

min/max are omitted above on purpose: a mana-backed bar auto-scales to Iron’s live max mana.

Multiplayer and /reload. Each player’s bar and value are their own. When one player loses the power (an origin change, a revoke), only that player’s bar goes; every other holder keeps theirs, and a mana-backed bar is sent only to players who hold the power. After /reload, online players get their bars back straight away with their stored values intact, instead of waiting for a relog. Up to 2.2.27 neither held: one player’s revoke took the bar off every other holder’s HUD, a mana-backed bar was sent to every player, and a reload dropped bars until the holder relogged.

hud_render object:

Field	Type	Required	Default	Description
label	string	no	"Resource"	Display label on the HUD bar
color	string	no	"#55AAFF"	Bar color in #RRGGBB or #AARRGGBB hex format
should_render	bool	no	true	Origins compat: when false, hides the bar
always_render	bool	no	false	Keep the bar on-screen even when full. By default the HUD hides a full bar (the Apoli convention), but only after the resource has been spent once: a bar that starts at max stays visible until its value first drops, so a new player can see it is there. The client forgets that first spend on each join, respawn and origin change, so the bar shows again at those points until it is next spent. Set this to keep the bar visible all the time.
animated	string	no	—	Id of an animated bar FX preset, e.g. "neoorigins:fire". When set and the preset is loaded, the bar fill renders as an animated texture strip instead of the flat color.
tint	string	no	—	Hex color (#RRGGBB or #AARRGGBB) multiplied over the animated preset art, so one texture strip can be recolored per power. Ignored when animated is unset.

Animated bar FX presets:

Presets are resource-pack JSON under assets/<namespace>/bar_fx/<name>.json, looked up by the animated id. Because the bar render is entirely client-side, the preset and its texture ship in a resource pack: only the preset id travels in the power JSON; clients without the preset fall back to the flat color fill.

{
  "texture": "neoorigins:textures/gui/bar_fx/fire.png",

  "tile_height": 16,
  "scroll_speed": 24,
  "track_color": "#AA2B0900",
  "level_color": "#B3551500"
}

Field	Type	Default	Description
texture	resource location	required	The strip texture to scroll across the bar.
mode	string	"scroll"	Animation mode; only scroll is supported today.
tile_width / tile_height	int	64 / 8	Source texture dimensions in texels.
scroll_speed	float	24	On-screen pixels per second the strip drifts left.
track_color	hex color	#AA000000	ARGB backing drawn under the empty remainder of the bar.
level_color	hex color	track_color	ARGB backing under the filled portion: pick a brighter tone so the current level reads through transparent gaps in the texture.

See animated_bar_artist_spec.md for texture-authoring guidance.

neoorigins:variable

A named, persistent, always-hidden integer counter — a “local variable” for your origin. Unlike neoorigins:resource, a variable has no HUD bar, no regeneration, and no per-tick cost: it only changes when an action explicitly writes to it. It’s the lightweight way to track state (combos, charges, kill counts, stages) and gate other abilities on it.

The counter is stored per-player and saved across login sessions. Its storage key is the power’s own id, so it shares the same keyspace as resources: read it with the resource condition and write it with change_resource / set_resource, exactly as you would a resource. Because two powers can never share an id, a variable can never collide with a resource of the same name.

Field	Type	Required	Default	Description
start	int	no	0	Value seeded when the power is granted. Also the value reads fall back to before the first write. start_value is accepted as an alias. Clamped into min/max when those are set.
min	int	no	unbounded	Lower clamp applied to additive (change_resource) writes. Omit for an unbounded counter.
max	int	no	unbounded	Upper clamp applied to additive (change_resource) writes. Omit for an unbounded counter.

Declare more than one by adding a neoorigins:variable power for each counter. Because a read resolves the declared start value even before the power’s own seed runs (declarations are registered when powers load), the counter reads correctly no matter where it sits in the origin’s power list, but listing your variable powers first keeps intent clear (“declared at the start of the power stack”).

Example: a combo counter that powers a finisher

{
  "type": "neoorigins:variable",
  "start": 0,
  "min": 0,
  "max": 5,
  "name": "Combo"
}

Increment it on hit (via an action_on_event / change_resource of { "resource": "<this power's id>", "change": 1 }), gate the finisher ability behind a resource condition (comparison: ">=", compare_to: 5), and reset it with set_resource once the finisher fires.

---

neoorigins:slime_moisture

Custom resource bar (0.0–1.0 float) that drains passively over time, faster in dry biomes (desert, badlands, savanna) and much faster when on fire. Replenished by standing in water, rain or a water cauldron, and by drinking a water bottle. Triggers threshold effects: Regeneration above 75%, armor penalty below 10%, and damage-over-time at 0%.

Field	Type	Required	Default	Description
drain_per_tick	float	no	0.0004	Base moisture drain per tick
dry_biome_drain_multiplier	float	no	3.0	Drain multiplier in desert/badlands/savanna biomes
fire_drain_multiplier	float	no	10.0	Drain multiplier when player is on fire
water_refill_per_tick	float	no	0.005	Moisture gained per tick in water, rain or a water cauldron
water_bottle_refill	float	no	0.5	Moisture restored by drinking one water bottle; 0 leaves the bar unchanged
regen_threshold	float	no	0.75	Moisture level above which Regeneration I is applied
armor_penalty_threshold	float	no	0.10	Below this, -4 armor is applied
dot_threshold	float	no	0.0	At or below this, damage-over-time triggers
dot_damage	float	no	1.0	Damage per interval when at or below dot_threshold
dot_interval	int	no	40	Ticks between damage ticks

A cauldron is checked as a block rather than as a fluid, so the player has to be standing in it. A water bottle refills on the swallow, not on the click, and where a player holds more than one moisture power the most generous water_bottle_refill among them is the one that applies. Both affordances match what breath_out_of_fluid already gives aquatic origins.

Example:

{
  "type": "neoorigins:slime_moisture",
  "name": "Moisture",
  "description": "Must stay hydrated. Dries out faster in hot biomes."
}

---

neoorigins:slime_death_save

Death prevention mechanic for slime-themed origins. When the player would die with moisture above the threshold, they “split” instead: teleported to a random location, max HP reduced to 2 hearts, which gradually recovers over time.

Field	Type	Required	Default	Description
moisture_threshold	float	no	0.75	Moisture level required to trigger the save
teleport_distance	int	no	50	Horizontal blocks to teleport
teleport_y_range	int	no	10	Random Y offset range (±)
split_max_hp	float	no	4.0	Max HP while “split” (2 hearts)
recovery_ticks	int	no	2400	Ticks for HP to recover to normal (default: 120 seconds)

Example:

{
  "type": "neoorigins:slime_death_save",
  "name": "Slime Split",
  "description": "Instead of dying, splits and teleports away — but at 2 hearts."
}

Pair it with a companion slime_moisture power. Without one, moisture reads as 1.0 and never changes, so the save fires on every death. The save costs no moisture and has no cooldown.

---

neoorigins:slime_level_hp

Grants bonus max HP based on the player’s experience level. The bonus tracks your current level: it is recomputed from the level you have right now, so it falls when you lose levels and comes back when you earn them again.

Field	Type	Required	Default	Description
levels_per_hp	int	no	10	Experience levels needed per +1 max HP
max_bonus_hp	int	no	20	Maximum HP bonus cap

Example: +1 HP every 10 levels, capped at +20

{
  "type": "neoorigins:slime_level_hp",
  "levels_per_hp": 10,
  "max_bonus_hp": 20,
  "name": "Growth",
  "description": "Grows tougher with experience."
}

---

Composing power sets

Individual 2.0 power types are intentionally narrow so they can be combined. For a “rat”-style origin that marks small mobs it kills and gets a heal buff when attacking anything on the list:

• neoorigins:entity_set — declares the UUID set (e.g. mypack:kill_list)
• neoorigins:action_on_event with event: kill, entity_action: { type: neoorigins:add_to_set, set: mypack:kill_list } — appends victims to the set
• neoorigins:condition_passive with condition: { type: origins:target_in_set, set: mypack:kill_list } and entity_action: { type: neoorigins:heal, amount: 0.5 } — heals when attacking a marked target

Each piece is a separate power entry in the origin’s powers array. The entity_set power carries no behaviour on its own: it’s the shared name other powers read and write.

---

neoorigins:loot_pool_grant

Active power that rolls a vanilla loot table on activation and grants every rolled stack to the player. Lets pack authors deliver weighted, conditional, function-driven rewards through the full vanilla loot infrastructure instead of a flat item list, and (when FTB Quests is installed) reuse the same loot table as a quest reward via a tag-marker. The grant fires once per grant_id: after it lands, further activations with the same id do nothing until an origin reset clears the record.

Field	Type	Required	Default	Description
grant_id	string	yes	—	Unique id tracked so the bundle is granted only once per player. Shares the starting_equipment grant attachment so an Orb of Origin / /origin reset clears both.
loot_table	resource-loc	yes	—	The vanilla loot table to roll. Reuses the full vanilla loot infrastructure (weighted entries, conditions, functions, modifiers).
rolls	int	no	1	Times the table is rolled per activation.
bonus_rolls	int	no	0	Extra rolls added to rolls. Mirrors vanilla loot-pool naming.
active	string	no	""	Optional display-only translation key advertising which keybind slot the power expects (e.g. key.use_skill_1).
cooldown	int	no	0	Cooldown in ticks between activations (20 = 1s).

Overflow that does not fit in the inventory is dropped at the player’s feet; no stacks are silently lost. Empty rolls (a table that returns no items) do not consume the grant_id, so the author can fix the table and the player can re-activate.

FTB Quests soft-compat

When ftbquests is on the mod list, NeoOrigins listens for FTBQ’s QuestCompletedEvent. Any quest tagged

neoorigins_loot_pool_grant:<loot_table_id>

routes through the same LootPoolGrantPower#fireLootPoolGrant pipeline on completion: the completing player receives the rolled stacks, with dedup keyed on ftbq:<quest_id>:<table_id>. Authors get vanilla loot-table reuse for both origin powers and quest rewards without any hard FTBQ dependency.

This is a soft-compat layer: it is not an FTBQ RewardType registration (which would require Provider-API hooks that vary across FTBQ minor versions). The tag-marker path is the supported integration; a RewardType upgrade is reserved for v2.2 once that API stabilises.

---

neoorigins:kill_loot_drops

Passive power that layers extra item drops onto the vanilla loot of any mob the holder kills: the bonus items appear as real drops from the mob’s corpse, flowing through the loot pipeline (drop events, other loot-modifying mods) rather than being pushed straight into the inventory. It is implemented as a NeoForge global loot modifier keyed on the killer (the mirror image of the mob-origin drop hook), so it fires only on entity-death loot tables, never on chests, blocks, or fishing.

One power can touch many mob loot tables at once: list an entry per mob type in drops, or match a whole category from a single entry with entity_tag / entity_types.

Field	Type	Required	Default	Description
drops	array	no	[]	The drop rules. Each entry rolls independently against the killed mob; an entry with no valid target or an unknown item is skipped with a warning at load time. Absent or empty is not a load error: the power simply drops nothing, so it is worth setting.

Each entry in drops takes exactly one target form plus an item:

Field	Type	Required	Default	Description
entity_type	resource-loc	one of	—	A single exact mob type, e.g. minecraft:zombie.
entity_tag	resource-loc	one of	—	An entity-type tag, e.g. minecraft:skeletons, matches every type in the tag. Write it without a leading #; with one the entry is skipped with a warning.
entity_types	array	one of	—	An explicit list of exact mob types.
item	resource-loc	yes	—	The item to drop. An unknown id skips the entry.
chance	float	no	1.0	Probability in [0,1] that this entry drops on a matching kill.
count	int	no	1	Stack size dropped (minimum 1).

Exactly one of entity_type / entity_tag / entity_types must be set per entry. The drop only rolls when the killer is a player who holds the power: mob-on-mob and environmental deaths are ignored. A player may hold several kill_loot_drops powers at once (e.g. one per origin tier); their rule lists are concatenated, and revoking one leaves the others intact.

Worked example: Head Hunter

data/neoorigins/origins/powers/head_hunter_drops.json:

{
  "type": "neoorigins:kill_loot_drops",
  "name": "Head Hunter",
  "description": "5% chance to drop the matching head when you kill a zombie, creeper, skeleton or piglin.",
  "drops": [
    { "entity_type": "minecraft:zombie",   "item": "minecraft:zombie_head",    "chance": 0.05 },
    { "entity_type": "minecraft:creeper",  "item": "minecraft:creeper_head",   "chance": 0.05 },
    { "entity_type": "minecraft:skeleton", "item": "minecraft:skeleton_skull", "chance": 0.05 },
    { "entity_type": "minecraft:piglin",   "item": "minecraft:piglin_head",    "chance": 0.05 }
  ]
}

The same idea, hooking every undead type from a single entry:

{ "entity_tag": "minecraft:undead", "item": "minecraft:bone", "chance": 0.25 }

Activation

The hook is a global loot modifier, so it has to be switched on by a carrier file: unlike mob_origin_drops, the mod does not auto-generate one for you. Ship these two files alongside the power (the Head Hunter example includes both):

data/neoforge/loot_modifiers/global_loot_modifiers.json:

{
  "replace": false,
  "entries": [ "neoorigins:kill_loot_drops" ]
}

data/neoorigins/loot_modifiers/kill_loot_drops.json:

{
  "type": "neoorigins:kill_loot_drops",
  "conditions": []
}

replace: false makes NeoForge merge the entry list additively across packs, so this coexists with the mod’s own mob_origin_drops carrier and any other pack’s modifiers. The per-power drops live in the power file, not here: this carrier is a data-free on-switch, so one carrier covers every kill_loot_drops power in the pack.

KubeJS bridge powers

These two types delegate power behavior to JavaScript handlers registered from a KubeJS startup_scripts/ file. They only function when KubeJS is on the mod list: the power JSON references a js_id, and the script registers the matching handler via the NeoOrigins.* bindings. If no handler is registered for the id, the power is inert.

They are registered on 1.21.1 and, from 2.2.24, on 26.1. They are absent from the 26.2 build because KubeJS itself has no 26.2 release to build against, and a power file naming an unregistered type is dropped whole at load. See KUBEJS.md.

neoorigins:js_custom

A passive power whose lifecycle hooks run JS. Register the handler with NeoOrigins.registerPower(id, {onGranted, onRevoked, onTick}); any hook the JS object doesn’t supply defaults to a no-op.

Field	Type	Required	Default	Description
js_id	string	yes	—	ID of the JS handler registered via NeoOrigins.registerPower

{
  "type": "neoorigins:js_custom",
  "name": "Scripted Aura",
  "description": "Behavior supplied by the pack's startup script.",
  "js_id": "mypack:aura"
}

// startup_scripts/powers.js
NeoOrigins.registerPower('mypack:aura', {
    onTick: player => { /* runs each power tick */ }
})

neoorigins:js_active

A keybind-activated power whose onUse runs JS. Register with NeoOrigins.registerActivePower(id, {onUse, onGranted, onRevoked}). onUse(player) must return a boolean: true consumes the cooldown and hunger cost, false is a no-op (nothing is consumed). Cooldown and hunger cost behave exactly like every other active power.

Field	Type	Required	Default	Description
js_id	string	yes	—	ID of the JS handler registered via NeoOrigins.registerActivePower
cooldown_ticks	int	no	20	Cooldown between uses in ticks (20 = 1s), consumed only when onUse returns true
hunger_cost	int	no	0	Food/exhaustion points consumed on a successful activation (onUse returns true)

{
  "type": "neoorigins:js_active",
  "name": "Scripted Blink",
  "description": "Teleports via the pack's startup script.",
  "js_id": "mypack:blink",
  "cooldown_ticks": 100
}

// startup_scripts/powers.js
NeoOrigins.registerActivePower('mypack:blink', {
    onUse: player => {
        // return true to consume cooldown + hunger, false to no-op
        return true
    }
})
