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.

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.
