This is Vadriel's half-resurrected form. It resembles a giant light blue mist face with dark red eyes. He cannot speak, he can only growl.
Vadriel will float around the battlefield. He has several attacks. When he glows yellow, several beams will erupt from his body in a random pattern. When he glows red, he will dash towards the player. He can also shoot massive fireballs from his mouth, and shoot three orbs from his eyes, which will shoot beams in random directions. When nearly dead, he can shoot a massive destruction ray. He has 9999 HP. His theme is Great Gate of Darkness.
