Do you use one type of vampire or a spread of them?
If it's one type what did you go with?
Originally I wanted to lean towards the traditional, linea dracula type. Now i'm toying with a weird inter-dimensional, weird-science, phasing-in-and-out type of creature (still working on the visual). I'm also terrible at thinking up monster stats, because I'm scared i'll overdo or underdo the potency. I'm not big on TPK. How did you fare?
