The Wither Skeleton skull is a rare item in the game Minecraft. It is dropped by Wither Skeletons, which are tall, dark variants of skeletons found in nether fortresses. Players can collect these skulls to summon the Wither, a powerful boss mob. To obtain a Wither Skeleton skull, players must defeat Wither Skeletons, but the drop rate is low, typically around 2.5% without any enhancements. Collecting three skulls is necessary to create the Wither, making them valuable for players seeking to challenge this formidable enemy.
