Wither Skeleton

Wither Skeletons are mobs that were added in Update 0.12.1. They spawn in the Nether in Nether Fortresses, and are Nether equivalents of Skeletons.

Attack
Wither Skeletons walk slowly when idle, but when they see the player, they persue quickly and attack using a Stone Sword. It has a chance to inflict the player with the Wither Status Effect, which is like Poison, but can kill the player.

Combat
Wither Skeletons are best fought using a Bow, as getting close may be lethal to the player, but using a Diamond Sword is also a considerable option.

Trivia

 * Wither Skeletons have a 1/40 chance to drop their skulls.
 * Their head is used to summon a boss in Minecraft, but isn't added yet.
 * Wither Skeletons are bigger size in than a normal Skeletons.
 * There is no Wither Skeleton Spawn Egg added. However, the player can spawn a Wither Skeleton with a Skeleton Spawn Egg, but the player must be at the Nether to spawn one as they cannot be spawned in the Overworld.
 * Using a Skeleton Spawn Egg in the Nether has a 30% chance of spawning a normal Skeleton.
 * At rare times, Skeletons naturally spawn in the Nether since Wither skeletons are spawned using the Skeleton Spawn Egg.
