Wither Nerf
by Jamma003
Wither Nerf changes how the Wither boss moves, so a fight with it is less of a cheese exercise on Fabric 1.20.1 servers.
What it does
The mod targets the vanilla Wither, whose movement is described by its author as floaty and hard to pin down. Wither Nerf slows how fast the boss floats and stops it from changing direction on the fly, which gives players a little extra room when they fight it. Running directly underneath the Wither, a common way to gain distance, no longer gets the player overshot once the boss turns around.
Wither Nerf is server-side only, so players join a server running it without installing anything. Its only published build targets 1.20.1 on Fabric, and it is released under the MIT License and is open source. The source code and issue tracker are public. Its author recommends pairing it with Wither Fix, which stops the Wither from being cheesed by players who exploit its positioning.
Key features
Slower floating movement
The Wither floats more slowly, so it is easier to track while it moves around the arena.
Fixed turning behavior
Once changed, the Wither cannot change direction in the way vanilla allows, which steadies its attacks.
Health-based threshold
The changes apply above 50 percent health, leaving the final phase of the fight unchanged.
Compatible with Style Wither
The author notes that the changes fit alongside Style Wither, which adds melee phase 2 attacks.

Use cases
Fights that are hard to track
Players who find the vanilla Wither floaty and hard to hit can use the mod to make the boss easier to follow.
Modpacks removing cheese
Pack authors who removed Wither cheese strategies and found the boss too strong can use the mod to rebalance it.
Who it’s for: Server owners and modpack authors who want a gentler Wither fight on Fabric 1.20.1. Players only need to join a server that runs the mod.
How it compares
Wither Skeleton Propagation is server-side only, open source under the CC0 1.0 Universal license, and targets Fabric 1.20 – 1.20.1, but it changes wither skeleton spawning rather than the Wither boss. Piglin Wither needs both client and server, is not open source, and is published under All rights reserved for the same Fabric 1.20 – 1.20.1 range.

What the author says
Java Wither is really not fun to fight, most people choose to cheese it. I removed the cheese in my modpack, but the Wither was too strong for the balance of the pack. This mod gives a little extra breathing room when fighting it.
