Korack grunts as he takes the wound, blood now seeping from the gash. His eyes dart back and forth at the oncoming undead and for the first time he realizes he might be in trouble. Then suddenly he smiles, a sheepish grin, before the giant brown bear appears behind him roaring out once more, it's form quickly merging with the shaman.

His body wavers, then wafts, turning into a smokey see through shape, of a giant brown bear.

Korack's going to use his Spirit Form. It turns him incorporeal. Granting him immunity to all nonmagical attack forms, a 50% chance to ignore damage from any corporeal source, and the ability to enter or pass through solid objects.

He loses his worn/natural AC, but gains his Cha mod as deflection AC. So his new AC is 15. This lasts for 1 minute.
