The Infernus Skull is a floating skull spawned by Infernon. It teleports around and shoots blasts of fire in the 8 cardinal directions. In normal mode, it is summoned when Infernon reaches half health. In expert mode, it is summoned at the start of the fight; and appears as a final phase of the boss fight.
