The term 'Vampire Vanquisher' refers to someone who is tasked with the job of eliminating vampires. This can be done in two ways: by using a STAKE or by slaying them. A STAKE is a wooden object, usually pointed, that is used to pierce the heart of a vampire, thus killing it. A SLAYER is someone who uses physical force to kill a vampire. Both methods are effective in vanquishing vampires and have been used for centuries.
