Vampire Stone

The Vampire Stone is a accesory dropped by vampires during solar eclipses with a same rarity as moon stones from werewolves and neptune's shells from creatures of the deep. It turns the player into a vampire at night, and if the player tries to fly, it turns them into a bat, where they can fly for as long as bat wings can before descending. They also (while a bat) make all attacks inflict bleeding. However to fly as a bat they must have no flying boots or wings.
