Can you be a werewolf and also become a vampire? I'm just curious?
I wouldn't be a vamp anyways, it was annoying in oblivion!
Soooo I am not sure if this still works the same in Skyrim, as it did in norrowind, but the work around was while you were afflicted with Vamprisim, there was a quest to turn you into a Werewolf, resulting in the benifit of both. The downside was the sideways head glitch, which was only a graphical amusment.
Now seeing as there is a quest to become a werewolf, I have yet to come across one to be a vamp. It might be out there, and it MIGHT work, either which way.
In other words, not sure but it is plausable!
Hope this helps! And by help, I meen break the game..again. Haha!
