Vampire Hunter

Your knowledge on vampires has gifted you a sixth sense of sorts, with which you can use to detect subtle signs of their presence. Additionally, thanks to your experience in hunting the abominations, you are now completely immune to being charmed by them.

You are always aware if there is a vampire within 30 feet of yourself. While you may not be able to sense their exact location, you are also capable of discerning how many are in your presence.
