Luminox (Heroic)

Strategy

 * 1) Luminox has a knockback, and there are holes in the floor, so consider positioning.
 * 2) Every 20%, Luminox emotes "The Core Guardian plants its feet as it prepares to fire a volley of short-range missiles!" then launches "Manaetic Missile's Manaetic Explosion", which does enormous damage. The missiles move slowly and explode after 10 seconds, and just running away around the edges of the room until they self destruct works well.
