The Abbadon starts out with NulAll, making elemental magic useless. Also, the Abbadon uses Pharaoh's Curse to inflict multiple status effects to the one character. Finally, it uses Emblem of the Cosmos, which does heavy damage to all characters, as its ultimate attack. However, this battle is not very hard if the player has the Celestial Weapons.
