infestation potion
by afxcfgg
Infestation Potion is a Forge backport that brings the Infestation status effect from newer Minecraft updates to version 1.20.1.
What it does
The mod adds the official Infestation status effect, which was introduced in a newer update, so players on 1.20.1 can use it without moving to a later release. It is aimed at players who stay on an older version because other mods they rely on have not been updated. Client and server both need the mod, and the files are published for Forge on 1.20.1 only, under the MIT License, which is not an open source license.
Key features
Potion effect in 1.20.1
Adds a potion that applies the Infestation effect, which turns mobs hit by it into silverfish-like swarms.
Silverfish-based setups
The effect suits builds that use silverfish, such as automated experience farms where allays collect the drops.
Infestation mechanics
Infested mobs spread the effect to nearby creatures, so one potion can affect a group.
