Infestation Potion Mod
by Autisto
Infestation Potion Mod adds a custom potion that makes afflicted mobs periodically summon silverfish around themselves, for players who want a cursed brewing effect on Fabric.
What it does
Once a mob is afflicted by the Infestation Potion effect, it lasts 3 minutes. During that time each hit the mob takes has a 10% chance to trigger a spawn of 1 to 3 silverfish around the infected creature. The potion is brewed by combining an Awkward Potion with a Stone Brewing Stand, and Splash and Lingering versions can be upgraded with Gunpowder and Dragon's Breath.
The mod is published for Fabric only, across six release versions 1.20.1 – 1.20.6, and the latest file is 1.0.0 for 1.20.6, released on 2025-02-08. Servers that run it need every player to install it too. The code is under the MIT License, and the project is not open source in the sense of a public repository claim, so the license is simply the MIT License. The mod is compatible with Splash Lingering Potions for area-based infestations.
