Configurable Mob Potion Effects
by Serilum
Configurable Mob Potion Effects lets server administrators set permanent potion effects on living entities and effects that apply to a target mob when it damages someone.
What it does
Two config files control the behavior: permanenteffects.txt sets effects that a mob keeps at all times, and ondamageeffects.txt sets effects applied to a player or other target when the mob attacks it. Each entry is given a level and a duration, and a level of 0 disables that entry, which is also the default for every setting.
The files are generated on first load, and after that they list the possible entities and potion effects, including modded ones. Changes are made by editing a line and reloading with cmpe reload, so the game does not need a full restart to pick up new values. Required dependency: Collective, which must be installed alongside it on each loader.
Only the server needs it, and players join without installing anything. The mod is published for Fabric, Forge, NeoForge and Quilt across 29 release versions, 1.16.5 – 26.3, and the code is licensed as All rights reserved, so it is not open source.
Key features
Permanent mob effects
Any listed mob can be given a permanent potion effect, with a chosen level, such as permanent speed on slimes.
Damage-triggered effects
A mob can apply an effect to its target on each hit, for example poison or levitation for a set number of seconds.
Modded entities and effects
Entities and potion effects added by other mods appear in the config files once they are loaded, and can be set the same way.
Zero disables an entry
Setting a level to 0 turns off that entry, and every default is disabled until an administrator changes it.

Use cases
Changing a server's mob behavior
Administrators can make a mob type faster, tougher to flee from or more dangerous on contact, without writing a datapack.
Who it’s for: Server owners and modpack builders who want mobs to behave differently from vanilla and prefer editing text files over scripting.
