Unless it's part of a quest, all you get is a full belly.
Cool. Thanks.
When in Human Form, yes it is. Which is why I love it. I look like a normal vamp, but with the promise of an epic transformation beat-down on my enemies if the fight starts going too badly.

No it's not. As I stated previously in the thread
"This is not really the case. They made some adjustments. It's actually easier to deal with than a regular vanilla vampire. You take half the weakness to fire than that of a vanilla vampire, you don't get attacked by everyone when you are a stage 4 vampire, and this last one I haven't taken the time to confirm yet, but I would assume that since you take half the weakness to fire that you may take more or less of a hit to your stats when out in the sunlight. Otherwise it's the same."
