Configurable Mob Potion Effects (Legacy Fabric)
Configurable Mob Potion Effects mod allows server administrators to customize potion effects for all creatures in Minecraft. This is a server-side addon that works entirely on the server and doesn't require client installation.
Main Features
With this mod you can:
- Assign permanent potion effects to any mobs
- Set effects that players receive when attacked by specific creatures
- Work with both vanilla and modded entities and effects
Configuration
The mod creates two configuration folders in the ./config/configurablemobpotioneffects/ directory:
permanenteffects.txt - for permanent creature effects ondamageeffects.txt - for effects when dealing damage


Practical Examples

Let's make all slimes incredibly fast by setting a permanent speed effect level 50:
