About the Mo-Variants data pack
Not enough mobs for your taste?
Introducing Mo-Variants!
This datapack by Rainy Realm Creations brings all new mobs and variants to the game.
There are multiple categories of variants:
- Normal - These variants/mobs aren't really special in any way, but they are still unique and add to the game!
- Ambient - These variants/mobs are to help with the ambiance of a world.
- Bosses - These variants/mobs bring more challenge to the game, but are also a lot more rare to encounter.
- Seasonal - These variants/mobs are designed to appear during specific times of the real life year. More info down below!
- And more...

Mo-Config!
Run the following command to customize your experience!
/function mo-var:config
You can enable/disable some integrations, toggle each variant's spawning, and even change their spawnrates!
Mo-Items!
Some custom mobs/variants will drop some unique items.
The Forgotten miner drops a helmet that gives night vision, the Undead Barbarian dropping a unique battle axe, and a decent few more!
Some custom items will be split out of the pack in a future update to increase the ability for you to customize your experience!
Integrations:
Mo-Variants contains several integrations with other packs. Please bear in mind sometimes this list may be a little behind.
All integrations are always optional, and only exist to make your personal experience better.
- Time Lib Integration for 1.20.3+
- This integration will allow the automatic enabling and disabling of seasonal variants.
- Can be toggled in the config in case you need this pack for something else, but don't want seasonal variants.
- Horde Nights Integration for 1.20+
- This integration reduces issues that cause some variants under the Horde Effects to become nearly impossible to outlast.
There may be more, however these are the only tested integrations. If you would like a proper integration with another pack, please reach out!
