vampiric powers that can have you potentially have more than average power but you need to drink blood in order to regenerate? also human blood > animal blood and fresh blood (from da neck neck yo) > prepackaged blood?

I'm assuming you're just talking about powers that happen to resemble a vampire and not actually being a vampire? Anyway, drinking blood is a very random and specific way to get energy, but I suppose that wouldn't be bad. The only problem is where do you go from there? You can't really do anything with just pure energy, you need some actual abilities in order to actually use the energy. It would be like having an unlimited supply of gasoline but not owning a car
