Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

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.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

Increased Health Pool: The Wither now boasts a health pool of 600 hearts.
Nether Blitz: The Wither can periodically perform a high-speed dash toward its target, accompanied by a shockwave that applies Wither damage and effects such as blindness and slowness to nearby entities.
Skeleton Summoning: When its health drops below certain thresholds, the Wither will summon Wither Skeletons to assist in the battle.
Enhanced Wither Skulls (Nether Blast): The Wither's skull projectiles now deal 25% more knockback.
