Orion is the third Constellation. The Boss at level 5 is a humanoid enemy that starts out walking around on the inside of the circle that makes up the arena. He will throw balls of sun at you and summon a circle of icicles around the player. In order to do any damage to him, you must break his ice shield by shooting at one of the suns that he creates and having the flames hit him. At half health, his upper half will split away from the lower half. The upper half will no longer be constrained to the walls, and the lower half will begin kicking at you.
