Change Vampire to something unique

[Ikkonoishi]

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.

They should also sparkle in the light if they are too pathetic to feed.
