I have two characters, one is Vet rank 2 and is a Vampire rank 10, the other is a Vet rank 4 and WAS a Vampire rank 10.
I decided I wanted to try out werewolf so last night I went and cured myself, found a wild werewolf and got infected, finished the quest and grinded up my WW form to rank 5 whilst questing in Eastmarch (V4 zone for AD).
I got devour, but I haven't gotten to use it yet. Now as a vampire you can literally ONLY feed on humans/elves. No undead, no daedra, nothing similar in shape to a human but not a human.
Is this same limitation on the Werewolf? It just says "can devour humanoids"...so does that mean anything with two arms, two legs and head of reasonable humanish description? (Trolls, Daedra, Undead, Humans, Elves, even Atronochs etc..)
