the most common belief is that eating garlic will kill a vamp as well as touching it, and since they are fictional the most common belief is the correct one.

there should be a super boss and the way you encounter it is if you have one character left to get at the end of a level than the next level is a boss fight with that creature but instead of the normal thing all it's stats are multiplied by ten!
