Miscellaneous Mobs Server Utility

Summary

Mobs Properties Randomness lets you add/change many properties to mobs on spawn, and, with events, when other stuff happens, such as on attack, on tick or on death with data packs.

This mod requires InsaneLib

As of 5.0.0 and up the mod (and its dependencies) now work server side only, so with MPR server you can connect with a vanilla client.

The mod

The mod does nothing on its own, you have to make a data pack: click here to get started (please note this is for latest version, click here for a list of versions)
You can also find a video tutorial playlist below.

Some stuff you can do:

  • Potion Effects
  • Attribute Modifiers
  • Equipment
  • Effect immunity
  • NBT
  • Events (attack, kill, target change)
  • Presets (for creating stuff like bosses)
