Wither Skeleton Skulls have a 1/40 (2.5%) chance to be dropped by a Wither Skeleton upon death. They are the only Mob Heads obtainable legitimately in Survival Mode, and are mostly aesthetic. However, they have one other use: When three are put on a T-shape of Soul Sand, the deadly Wither is created. Wither Skeleton Skulls were added in the Pretty Scary Update.
- When broken, Wither Skeleton Skulls release Soul Sand particles, like all mob heads.
