The Wither is a boss in the Minecraft: PlayStation Editions. It is spawned by placing a block of soulsand, and then placing one above and one on each side. Three wither skeleton skulls, dropped by Wither Skeletons, then need to be placed above the blocks to create it. The wither has 300 HP, the most of any Vanilla Minecraft mobs.
The Wither has three heads, each shooting mini heads that will blow up once it hits a block, mob, or player. It is recommended to bring several potions of instant healing and strength to have the player be able to regenerate health, and to spawn the Wither in a secluded place, like a cave, so none of the player's valuables are destroyed.
