About this Mod

This mod makes it so that once the wither spawns, it gets deleted and a new wither is placed that is already full health and has no invulnerability, so that you dont have to wait when farming multiple withers at a time!

This mod currently supports from 1.20.5 up to 1.21.11. And works in servers and singleplayer.
