Use any holy attackers you may have. You should have no problem with him unless your party is low level.



An unidentified esper that was sealed away in an enchanted mountain of Dirnado. With pitch black wings, it had a sinister appearance, and it is no wonder that the locals fear it as they would a demon. Having sealed it away ages ago, they have forgotten that it was an esper. With its own unique concept of values free from human morality, this esper lends the powers of darkness only to those who strike its fancy.
