I just ****ed him with Valkyrie. Threw Ninja, Valkyrie, and 1 other at him and healed up Ninja or Valkyrie again. Was thinking about using wraith next, but tried Vampire. They have the same odds as Valkyrie, Aether, Mismoth, Boo,zombie, witch, naga, Peacock, Headless, Black swan, Kitsune.
25% chance.
Also someone used Spirit(4) against him and won. And Hypnotic and Justice too. Good luck, Kami!
