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.

Spawning
Wither skeletons spawn in nether fortresses at a light level between 0 and 11, in groups of 4[needs testing]. They can spawn on wither roses due to their immunity to the damaging effects.

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, it is inflicted with the wither effect for ten seconds in any difficulty, which turns the health bar black and decreases it by  every two seconds, similarly to Poison, except that it can kill.

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 unenchanted. 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.
