This bug is so fun I almost hate to report it, but if you save the game while shapeshifted you will permanently become that creature, to the point where it will reset your maximum health to that of the creature you shifted into. Additionally, you can charge and fire your staff, though a charged melee doesn't seem be any stronger; wear items, and cast spells. Shifting into a new creature still acts normally, but when it wears off you will still be what you were turned into.

Somewhat related to this I was a little disappointed that a suicidal monster ability with the contingency edge doesn't actually do anything that I could tell.
