After reading through all the books that I can find (CoD, DtD, DSG, Iface, etc.), I cannot find any rules for Angelic forms.
Black Nathaniel in CoD states that he flies around and he has black wings. However, I see no stats for it (maybe I missed it?).
What are thoughts on using the Demonic forms as a template? Just spin it as an angelic theme (i.e. use feathery, smoke-like or mechanical wings as opposed to using bat-like wings). Use the "claws and fangs" or "barbed tail" for a "razor wing attack"... that kind of thing.
Does anyone have any other suggestions?
