Wither Skeleton

Wither skeletons are tall black variants of skeletons equipped with stone swords that inflict the poison-like Wither effect. They are found exclusively in nether fortresses and are the only source of wither skeleton skulls, as well as the only renewable source of coal.

Spawning
Wither skeletons spawn in nether fortresses at a light level between 0 and 7, in groups of up to 4. They are the only mobs that can spawn inside wither roses due to their immunity to the damaging effect.

Halloween
On Halloween, wither skeletons have a 22.5% chance of spawning wearing a and a 2.5% chance of spawning wearing a. This is not dropped, even when killed with Looting.

Withers
The wither spawns 3-4 wither skeletons when below half health on normal and hard difficulties.

Jockeys
Spiders and cave spiders spawned in the Nether have a 0.8% chance of spawning a wither skeleton on their back and form a spider jockey. Spiders do not naturally spawn in this dimension.

Drops

 * 0 to 2 s. The maximum drop is increased by 1 per level of Looting, for a maximum of 0 to 5 bones with Looting III.
 * There is a $$ chance to drop a single . Each level of Looting increases the maximum drop by 1, so that Looting I drops 0-2 coal with an average of 0.75 coal per kill, Looting II drops 0-3 coal with an average of 1.2 coal per kill and Looting III drops 0-4 coal with an average of 1.67 coal per kill.
 * 2.5% chance to drop a when killed by a player or tamed wolf. Looting increases the chance by 1% per level or 2% per level, for a maximum of 5.5% or 8.5% chance with Looting III. Their skull is always dropped if killed by a charged creeper, though only one head drops if many are killed by the same charged creeper explosion.
 * 8.5% chance of dropping their unenchanted stone sword which has a random durability. This chance increases by 1% per level of Looting, for a maximum of 11.5% chance with Looting III.
 * experience orbs when killed by a player or tamed wolf, and an additional is dropped per piece of naturally-spawned equipment that does not drop upon death.
 * Because all wither skeletons spawn with a stone sword, each of them effectly drop if the sword is not dropped.
 * If the wither skeleton does drop its stone sword, it drops the default instead.
 * If a wither skeleton wearing a carved pumpkin or jack o'lantern is killed using a tool enchanted with Looting, there is a chance equivalent to the level of Looting used to drop the carved pumpkin or jack o'lantern, a maximum of a 3% chance of a drop.

Behavior
Wither skeletons wander aimlessly when idle, but sprint to attack players, snow golems, iron golems, baby turtles, piglins, and piglin brutes. They flee from wolves but retaliate if attacked.

When an entity is attacked by a wither skeleton in any difficulty, it is inflicted with the Wither effect for ten seconds, which turns the health bar black and decreases it by  every two seconds, similarly to Poison, except that it can cause death.

Some wither skeletons may have the capacity to pick up dropped gear in Normal and Hard difficulties. The chance depends on regional difficulty, with up to 55% of them capable of picking up swords higher than stone tier plus any armor. Wither skeletons never take s; $$, if they hold a bow (which can be done with ) they shoot flaming arrows even if their bows are not enchanted. They cannot use crossbows.

Wither skeletons are immune to fire and the Wither effect. They still seek shade or water during daylight if they are in the Overworld although they do not burn in sunlight. Like most undead mobs, they sink in water but do not drown, are healed by Instant Damage and harmed by Instant Health effects, are immune to Regeneration and Poison effects and are not attacked by the wither.

$1/3$, the player can burn them by throwing a trident enchanted with Channeling during a thunderstorm.

Sounds
Wither skeletons use the Hostile Creatures sound category for entity-dependent sound events.
