I made a mod that adds a wild monster called Grace. They spawn in packs at dawn and dusk during winter and autumn. Could be added to “Crazy Cataclysm,” or not. Be warned, they are pretty dangerous.
If you want to try it, just drop in the mods folder. Works with the latest experimental versions, not any earlier versions.
Feedback is more than welcome.
