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 neoorigins-common.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.

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.
