The Wither is hostile to the player and all mobs except undead mobs (Skeletons, Zombies, Zombie Pigmen, Wither Skeletons and other Withers). When provoked by a skeleton or another Wither, they will only remain hostile toward each other for a moment before returning to friendly status. If spawned in The End, it will prefer to attack any nearby Endermen, but will attempt to pursue and attack the Ender Dragon if there are no nearby targets.
The Wither can move very quickly. Upon noticing a mob, the Wither attacks them with a projectile called the “Wither Skull”. Wither Skulls inflict a status effect called "Wither" on Normal and Hard difficulties. This effect is similar to poison, except that it can kill the player and turns the health bar black, making it difficult to tell at a glance how many hearts are still full. The wither is able to break any block, except Bedrock and End Portal Frame. It can also destroy Obsidian, which is well known for it's immunity to TNT and long mining time.
Each head fires individually, allowing a Wither to attack up to three different mobs at the same time. Withers need at least 5 block high airspace to fit, but as of snapshot 12w41b, they can no longer be trapped (and suffocated) in smaller rooms. Every few seconds, the Wither will break any block that comes into contact with it, except bedrock and end portal frame.
The Wither has an ability to destroy blocks, similar to the Ender Dragon's ability. When near any block that can be destroyed by a player, it will produce an audible smashing sound. For example, this could happen by having the Wither on one side of a wall, and the player on the other, so it would have to make a path through the wall to attack. The Wither will then instantly destroy a 3x3 hole in the wall to pass through it. The Wither also destroys a 3x3x4 space around itself 20 game ticks (1s) after being harmed.
The Wither's boss health bar is only shown when a player is looking in a direction of a Wither, and it can also be seen through walls when the player is looking in the Wither's direction. When reaching half health, the Wither will gain the "Wither Armor" effect, which makes it immune to arrows and potions, as well as having a visual effect surrounding it, similar to that of a Charged Creeper. While in this state, the Wither cannot fly. The Wither, when calm, cannot fly; it simply hovers above the ground and cannot "jump" up one block. When angered by the player, the Wither will fly at the same height as the player. Like other undead mobs (zombies, skeletons, etc.), the Wither is harmed by Potions of Healing and healed by Potions of Harming. It also regenerates over time.
