Wither

Overview

To spawn a Wither the player must create a T structure with soul sand (similar to the Iron Golem's spawn formation), then place 3 Wither Skeleton's heads on top. Once spawned, the Wither will glow blue and grow in size as their health bear fills, during this time they are invincible. Once their health bar is full the Wither will create a large explosion, powerful enough to kill a player in full diamond armor.

The Wither is able to crush blocks in it's way and shoot Wither Skulls out of each of it's head. When hit by a Wither Skull the player suffers from an effect known as "Withering" which causes the player to gradually lose health and obscures their health bar. Once the Wither's health is half-depleted it gains a power called the "Wither Armor" making it immune to all arrows, but lacking it's ability of flight. In addition to normal attack methods, it can also be damaged by the Potion of Healing and healed by Potion of Harming like other undead mobs. The Wither is hostile to all mobs apart from undead creatures (zombies, skeletons, wither skeletons, etc.).
