I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

Random Bosses

The WASD Random Bosses Datapack turns naturally spawned mobs in the world into bosses. It was inspired by an old mod that is similar in function. Bosses spawn with random power levels, random sizes, and loot based on difficulty.

Bosses spawn based on a configurable spawn rate.
Stats are determined at random.
Loot is based on the boss level. The higher the level the greater the loot.
