>Almost no passive effects when outside vampire form (At least being a werewolf gave you really good life regen)
>Having ANY silver items in your inventory smites you
>All of the perks upgrade your magic spells / vampire form
DESU I had already made up my mind to not become a vampire before this but that's a little more disappointing than I expected. The lesser powers you get are pretty strong but this is really only viable if you commit to a mage / offensive spellsword playthrough.
