This file is marked server-only.

Install Fabric API first. We found matching files for this game-version and loader setup.

About this project
What does MobRandomizer add?
Mob Randomizer Mod
A Minecraft mod that effectively randomizes mobs by remapping mob spawns.
Features
By randomly assigning every mob spawn another random mob, each mob will have another mob replace it for all its instances.
For example all piglins might get replaced by llamas.
Covers all types of mob spawns (natural, summoned, stuctures, ...).
Details
The randomized mappings are created when the world is loaded. They are based on the world seed, so using the same seed will yield the same results.
Mobs that cannot spawn naturally (giant, illusioner, ...) are excluded.
Configuration
You can choose mobs to be excluded from the randomization process.
When using the mod for the first time, a mob_randomizer.toml will be created in .minecraft/config.
There you can specify mob ids you do not want to be randomized. Example :
blacklist = ["ender_dragon", "wither", "giant", "illusioner", "zombie_horse"]
/!\ Warning : Randomizing the Ender Dragon may cause issues, it is recommended to leave it blacklisted.
