BossMutations

Every boss fight is now a question: which version did we get?

Part of The Petrichor Protocol by Dileppy.

Teleporter and world bosses roll a mutation chance on spawn (25% base, +10% per loop, configurable). A mutated boss announces itself in chat - then plays by different rules.

The launch mutations

Mutation	Effect	Reward
Colossal	180% size, double HP, +30% damage, slower attacks	2x gold/XP
Frenzied	+40% speed and attack speed, -25% HP	1.6x
Shielded	Gains a barrier every 12s - burst in the windows	1.5x
Volatile	Explosion bursts at 75/50/25% health	1.6x
Splitting	Spawns smaller copies of itself at 66% and 33% HP	1.8x

Split children are half size with a quarter of the HP, and can never split again. Every mutation has its own toggle; pulse timing, burst damage, and split count are all configurable.

The Petrichor Protocol

This mod is a 3-star modifier in the Protocol. Install PetrichorProtocol and it counts toward your run's Risk Score and reward multiplier.

Pairs naturally with EnemyMutations - mutated trash mobs AND mutated bosses means nothing on Petrichor V is ever what it seems.

Config

BepInEx/config/dileppy.bossmutations.cfg, generated on first launch.

Multiplayer

Mutations are rolled by the host, so the host must run this mod. Singleplayer is the primary supported mode.
