Minotaurs only spawn from the Minotaur Spawner in the Twilight Forest Labyrinth. The spawner is in a big room with 4 pillars, with one pillar containing the spawner, two pillars containing a chest, and the last pillar containing a TNT trap.
Minotaurs will occasionally moo, like a Cow. This will warn the player of the presence of a minotaur nearby. They have two attacks, both dealing 10 () points of damage:
Like most mobs, Minotaurs have a melee attack. If they are close enough, they will swing their axe at you, dealing damage.
Minotaurs also have a charge attack, in which they will pause for ~2seconds and then run quickly at the target and knock it up as well as hurting the target.
