The one vampire in my world fed on blood, but he would partake in normal human food and beverages, too. The sun didn't seem to affect him, nor did most bodily injuries.

[He isn't sure if this is normal for vampires since Lord Slayer never talked much about them. But Venom knows Slayer's not undead. Just hard to kill.]

Goodness, I didn't know there were so many myths surrounding vampires. That's rather fascinating!
