I agree with Magikeeper's revision of Devour, with the healing changed to be more like how it is now instead of all at the end.
EDIT: Two other things. One: Was "Flesh Calls to Flesh" based on the movie The Iron Giant? It seems relevant. Actually, a lot of the Giant could be a refluffed Ozodrin. Just replace the lasers with mouths that spit lightning.
Two: When changing from Worldly Guise to True Form, what things are kept? Would an Awakened Wolf Ozodrin changing to its True Form keep its bite attack, for example?
