Change Vampire to something unique

[Natsumehack]

Also, don't make blood just act as a resource for vampire powers. They should need that junk to stay alive. Treat it like a drug where they have withdrawal symptoms without it, possibly revealing their vampiric nature or even taking damage.

This would be a good idea to make them easier to catch; the longer they go without blood, the more their skin turns gray and their hair turns black, like a stereotype vampire

Maybe after sometime they begin to shake, and give off weird vampire only noises if they go too long.
