It is the evil counterpart of Zunraa, the protective spirit of Zen Daijun. This creature's two skills, Balthazar's Aura and Kirin's Wrath are very devastating to melee classes. It's best to stay away from him once it uses either of these. Either that, or interrupt them. He tends to frequently use Reversal of Fortune, as well as Blessing Of The Kirin, so stacking Hexes or high damage output is key.
