Evolution System

Origins evolve through three tiers as players accumulate mob kills. Each tier grants new powers and may replace or remove earlier ones. Classes do not evolve.

When you evolve, your health is restored to full.

Kill Thresholds (configurable)

Tier	Name	Default Kills
0	Base	0
1	Evolved	1,000
2	Ascended	2,500
3	Apex	5,000

Thresholds are configurable in config/neoorigins/gameplay.toml under [evolution]. A chat milestone message fires every 100 kills (also configurable).

Standard HP Progression

Most origins follow this pattern (1 heart = 2 HP):

Tier	Max Health Bonus
Evolved	+2 HP (+1 heart)
Ascended	+4 HP (+2 hearts): replaces Evolved
Apex	+6 HP (+3 hearts): replaces Ascended

Origins with non-standard HP or unique tier bonuses are noted below.

Config Options

[evolution]
    enabled = true
    tier_1_kills = 1000
    tier_2_kills = 2500
    tier_3_kills = 5000
    message_interval = 100

The Evolution Prompt

The prompt is checked on every mob kill, not only on the kill that crosses a threshold. Once the kill count is at or past the next tier’s requirement, a kill sends a chat prompt with clickable [EVOLVE] and [DECLINE] buttons. /neoorigins evolve accept and /neoorigins evolve decline do the same thing. Operators (permission level 2) can force a tier with /neoorigins evolve <player> <tier> (base, evolved, ascended, apex or 0-3) and check a player’s kills and tier with /neoorigins evolve query <player>.

Declining records the tier that was offered and stops that tier being offered again. The tier is not lost: it stays available, and /neoorigins evolve accept takes it whenever the player is ready. Only the declined tier is muted, and tiers are taken in order, so accepting it clears the record and the tier above it prompts normally once its own threshold is reached.

The declined tier is saved with the player, so the prompt stays quiet across a relog. Three things clear it: the player accepting that tier, an operator force-setting the tier with /neoorigins evolve <player> <tier> in either direction, and spending an Orb of Origin. The orb is the blunt one: committing it wipes essence kills, tier and the declined record together, so the player starts the ladder over from zero on their new origin.

Declining when nothing is on offer does nothing. If the player is already at Apex, or has not yet reached the next tier’s kill threshold, /neoorigins evolve decline reports “You have no evolution to decline.” and records no tier, so a decline typed early cannot mute a prompt that has not been shown yet.

Evolution by Origin

The Removed column lists the health bonus each tier supersedes. It is not the full removal list. Where a tier grants a stronger version of a power the origin already has, the weaker one is removed at the same time, so that only one source of the effect is ever live: Caveborn swaps its base night vision for the ascended one at tier 2, Merling’s base water breathing and night vision give way to the Ascended Conduit, and Abyssal and Verdant do the same at apex. Those swaps cost the player nothing and leave no gap, which is why they are not tabulated. Read the origin’s JSON if you need the exact list.

Datapack Customization

Evolution tiers are defined per-origin in JSON via tier_powers:

{
  "powers": [ "mod:base_power_1", "mod:base_power_2" ],
  "tier_powers": [
    {
      "tier": 1,
      "add": [ "mod:evolved_power" ],
      "remove": []
    },
    {
      "tier": 2,
      "add": [ "mod:ascended_power" ],
      "remove": [ "mod:evolved_power" ]
    },
    {
      "tier": 3,
      "add": [ "mod:apex_power" ],
      "remove": [ "mod:ascended_power" ]
    }
  ]
}

Pack authors can add, modify, or remove tiers for any origin.
