Alfred kept a cheat sheet tattooed on his left arm. Werewolves were silver bullets. Mummies were fire. Vampires were garlic and crosses and mirrors. And so on with the list. Not that he ran into these creatures all that much, but whenever he did, he had their weakness right there. When he ran into things that he hadn’t before, one of the locals would tell him what he needed, and he goes straight to the tattoo parlor and add to his list. Then the store. He always made sure to wear short sleeve shirts when he went out on adventures.
