Neutron
Make all mobs neutral, configurable per-player and per-mob!
Screenshots
About this Mod
Make mobs neutral to all players or specific players!
Most actions that make neutral mobs angry will still be in effect, such as staring at enderman and breaking beehives. However, not wearing gold armor for piglins and darkness for spiders will no longer anger them.
Neutral mode is disabled by default and must be activated with commands.
