New poll: What is your favorite vampire trait from folklore?

Suburban Vampire visitor ddurance suggested a poll about favorite vampire myths/legends. In the past, I've asked, "Which vampire cliches would you like to see laid to rest?", "What are the must-have vampire traits?", and "Why are we so attracted to vampires?" For the last two responses, sex appeal took the top choices.

Because sexiness wasn't originally part of vampire legends, I've added a little twist to this week's poll: "What is your favorite vampire trait from vampire folklore?" All choices derive from original vampire lore, not literature and movies. Which enduring feature do you enjoy most in your vampires?
