Wither Skeleton Basics

Wither skeletons spawn in nether fortresses, 2.5 blocks tall. Skull drop: 2.5% base (Looting adds 1%/level), Looting III = 5.5%. Need 3 skulls for Wither. Key: isolate from blazes, piglins, and regular skeletons.

Four soul sand, three skulls, one last click Wither: Build the T, Place the Last Skull Yourself The summon only fires when a player places the final skull. ☠ skull (top of the T) sand ☠ sand ☠ Cost 4 × soul sand 3 × wither skeleton skull Skulls must be placed by a player Dispensers will not trigger the summon. The T can face any direction. Fight it where it cannot break anything Bedrock layer or a sealed bedrock chamber It gains armour below half health — use Strength II and a strong bow or smite sword. It invulnerably charges for 10 s after spawning — back off, then fight.
Arrange four soul sand blocks into a T lying on the ground — three across the bottom and one stacked on the middle — then place a wither skeleton skull on each of the three upper positions. Nothing happens until a player places the last skull by hand, so dispensers cannot summon it. Spawn it in a bedrock chamber or at the bedrock layer: the wither destroys almost every other block, becomes armoured below half health, and spends its first ten seconds charging while invulnerable.

Fortress Modification

Cover fortress crossroads floor with slabs (limits other spawns). Keep 3-high spaces for wither skeletons. Dig 2-deep trench — stand inside, 2.5-tall skeletons walk in but can't hit you. Kill with Looting III sword. 10-30 skulls/hour.

Tip: Slab floors suppress other spawns without raising light level — wither skeletons need light <7. Most critical technique.

Wither Rose Trap

Wither roses (dropped when Wither kills non-undead mob) planted on ground deal wither damage. Cover fortress crossroads with wither roses — skeletons take damage walking over them, you just finish them off. Doubles efficiency with Looting III.
