Royal Variations

Royal Variations - a small mod that adds enhanced royal variations of vanilla mobs with their own characteristics and unique drops. All the mobs you will periodically encounter in the world, each has its own abilities and an increased amount of xp and drops, among which there are new items, each with its own use. The mod will slightly diversify and complicate your survival without loading the game with a lot of mechanics.

The appearance of specific mobs can be disabled through a game rule.

Mod requires GeckoLib to work.
