EnemyMutations
Every monster on Petrichor V can now spawn twisted. Same enemies you
know - new versions you don't.
Part of The Petrichor Protocol by Dileppy.
Enemies roll a mutation chance on spawn (12% base, +2% per stage, both
configurable). A mutated enemy looks different, fights different, and
rewards different.
The launch mutations
| Mutation | Effect | Reward |
| --- | --- | --- |
| Giant | 175% size, double HP, +30% damage, slower | 2x gold/XP |
| Tiny | 50% size, fragile, +50% speed, +25% attack speed | 1.3x |
| Frenzied | +50% speed and attack speed, -25% HP | 1.4x |
| Volatile | Explodes on death - watch your positioning | 1.5x |
| Treasure | Rare. Tanky, dangerous, announced in chat | 4x gold/XP |
Every mutation has its own enable toggle. Boss and elite mutation
gates, Treasure upgrade chance, Volatile blast damage and radius - all
configurable.
Design intent
Mini-boss moments without new models. A Giant Beetle is a wall. A
Frenzied Lemurian is a problem RIGHT NOW. A Volatile anything makes
you think about where you kill it. And when the gold Treasure message
appears, you have a decision to make.
The Petrichor Protocol
This mod is part of a modular challenge ecosystem. Install
PetrichorProtocol and every
Dileppy modifier you run contributes to a Risk Score, a challenge
tier, and scaled rewards - announced at the start of every run.
Stacks with the whole collection:
- Mutations + EnlargedEnemies = kaiju Giants
- Mutations + ShrunkenEnemies = microscopic swarm terror
- Mutations + ShrunkenSurvivor = survival horror energy
- Mutations + BiggerBullets = you will need them
Config
BepInEx/config/dileppy.enemymutations.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.
Changelog
- 1.0.0 - First release: Giant, Tiny, Frenzied, Volatile, Treasure.

Install & use Install: BepInEx plugin
- The archive from playbuff is the mod itself — usually a BepInEx plugin (a .dll or a plugin folder once unzipped).
- Recommended: use a community mod manager (such as r2modman) — pick this game, import the mod, and the manager sets up BepInEx and its dependencies for you.
- Manual route: install the BepInEx loader in the game folder, then drop the unzipped .dll or plugin folder into BepInEx/plugins/.
- Launch the game — the BepInEx console logs every plugin it loads; seeing this mod in the log means it is installed.
Mods with listed dependencies need those installed too, or they will not load. Options are usually changed in-game or in the plugin's config file.
Install these first, or the mod will not work:
