Instant Wither Spawn

by SiAmEs3

Instant Wither Spawn lets a Wither appear at once, with no invulnerability phase, so waiting for the boss fight to start is no longer needed.

FabricClient and serverMIT License1.20.5 – 1.21.11

What it does

A Wither summoned in the world skips its usual invulnerability stage and arrives at full health. When one is defeated, a new Wither can be placed straight away, which removes the wait between repeated fights. The mod runs on Fabric in both single-player and multiplayer, and both the server and every player need it. It supports game versions 1.20.5 – 1.21.11.

Key features

  1. No invulnerability stage

    The shield phase that normally follows a Wither spawn is removed, so the boss can be damaged right away.

  2. Immediate respawn

    After a Wither is defeated, the next one can be placed at once at full health, with no waiting period.

  3. Repeated fights

    Players can run several Wither battles back to back, which suits farming and repeated boss encounters.

What the author says

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.
