wither skeleton (minecraft)
Tall, black, undead skeletal hostile undead mob in Minecraft. Only spawns at Nether Fortress. Armed with a stone sword, instead of bow (weapon) like its white counterpart - skeleton (Minecraft). Its melee attack can cause deadly wither effect which can turn player's health-indicating heart on the HUD black and gradually depletes health. Has 20 health points (10 hearts).
The Wither (Minecraft) boss has chance to summon 3-4 wither skeletons on ground. Upon death it can either drop bone, coal, or stone sword with random durability point. This includes small chance (2.5%) of dropping its own skull.
