Swarm Origins

The origins are themed on ant-like, xenomorph and tyranid hive creatures. Each one trades a set of strengths for crippling weaknesses, such as fire vulnerability, no natural health regeneration from food, permanent severe hunger, and limits on using items, wearing armor or interacting with blocks. A human-like origin stays physically superior in exchange for a simpler balance.

Several origins can climb walls and ceilings, leap higher or move faster, fly with elytra, or detect nearby mobs through walls. Others act as fast specialists that halt or harass enemies, a stealth specialist, a ranged specialist that rains fire while dodging retaliation, a decently mobile tank that heals on its own, or a medic that is mostly unable to fight but keeps allies alive. Seven Tier 2 and two Tier 3 origins evolve from a base origin after time, and each active origin has three active abilities and two passives.

The mod is meant for PvP roleplay on servers, and it makes singleplayer harder on purpose. Evolving takes about 15 minutes, and progress appears while holding Shift. Changing caste resets the current Tier after 10 minutes and downgrades the previous Tier too. Origins Backgrounds and similar variants are not part of this mod. Swarm Origins requires Origins (Forge) and Pehkui, and it runs on client and server, so the server and every player need it. Files are published for Forge only, for Minecraft 1.20.1.
