I’m going to begin my discussion of vampires with a digression: Years ago, I read a book titled (I swear I’m not making this up) Sherlock Holmes vs. Dracula: The Adventure of the Sanguinary Count. It was written by Loren Estleman in the style of Arthur Conan Doyle, and as I recall, it was less cheesy and far more entertaining than you might assume . . . although I don’t think I’ve read it since I was in college, so take that with a grain of salt.
Anyway, there’s one bit of that novel that sticks in my mind as being particularly cool: At one point, Dracula walks right into Holmes’ room, in the middle of the day, and Holmes expresses surprise that Dracula can go out in broad daylight. Oh, sure I can, Dracula says; it’s just that I don’t have any of my supernatural powers when I do.
I thought that was an interesting spin on vampire abilities. One of the crucial elements of horror is exploiting the fear of the unknown: we’re most afraid of a monster when we’re not sure what it is, what it can do or how far it can pursue us. One of the best ways to spice up a D&D game is to take familiar monsters and give them unfamiliar powers, or have the familiar powers manifest in unfamiliar ways. Trolls, for example, are great for this: use the variant that allows severed limbs to keep moving and even fighting independently, and have the troll periodically pick up its limbs and stick them back onto itself, and watch your players wig out. (You may already be aware that this version of the troll originated with a scene in Three Hearts and Three Lions by Poul Anderson.)
It’s so taken for granted in our popular culture that vampires are burned by sunlight, the thought of a vampire who’s merely weakened by it, not hurt—let alone destroyed—would never occur to most of us. The vampire in the Monster Manual is the conventional burned-by-sunlight variety, but what if you removed that weakness and substituted one that merely disabled the vampire’s special features in daylight?
Try this sort of variation out—if not with a vampire, then with some other monster whose powers players assume they already know.
