About this project
What does Chaos Moon add?

During the rare Chaos Moon event, the weight of Born In Chaos mob spawns will be greatly increased, and during a Super Chaos Moon, all mob spawns will increase by a large amount as well, leading to a world overrun by chaos. During both moons, drops from BIC mobs are doubled.
All credit for Enhanced Celestials goes to CorgiTaco.
Requires: Born In Chaos
