Ultra Rare Wither Skull Rates
by Der_Erlking
Ultra Rare Wither Skull Rates is a server-side datapack that makes Wither Skeleton Skulls far rarer in vanilla loot tables.
What it does
The datapack changes only one loot table, the one that controls how often a Wither Skeleton drops its skull. Its base drop chance is 0.5 percent, five times rarer than vanilla, and Looting III raises it to 2.0 percent per kill. Across 200 wither skeletons an average skeleton-killing player collects about one skull, and with Looting III the figure is about one skull per 50 wither skeletons. Bones and coal drops stay untouched, so other loot from those mobs is unchanged.
The datapack is built to be lightweight and works standalone. It is also a small companion for Wither's Wrath, an optional dependency, and the author recommends pairing the two so the enhanced Wither fight stays special and does not become too hard to fight. Wither skulls can still be summoned, so the rarity change mostly affects survival farming and loot runs.
Files are published for Fabric, Forge, NeoForge and Quilt, for four game versions: 26.1, 26.1.1, 26.1.2 and 26.2. The latest file, 1.0.0, targets 26.2 and was released on 2026-07-11. The datapack is server-side, so only the server needs to run it, while clients may leave it out. The mod is released under All rights reserved and is not open source.

What the author says
A lightweight datapack created as a small companion addon for the popular datapack/mod WithersWrath. It makes Wither Skeleton Skulls significantly rarer so that the enhanced Wither from WithersWrath doesn't become too easy or spammable to summon. Bones and coal drops are completely unaffected.
