Trivia

 * If the player clears out a room and saves at least one enemy, they can save, quit, and then continue the run to enter the same room with enemies reset. The counter for Charm of the Vampire is saved along with the game, meaning the player can farm the same room for Red Hearts.
 * This item is used in Have a Heart (challenge #25).
 * A vampire is a being from folklore who subsists by feeding on the life essence (generally in the form of blood) of the living.
 * In folklore, a vampire leaves no reflection because it has no soul. This is why Charm of the Vampire removes Isaac's reflection.
 * If the player dies while one of their tears is on track to kill an enemy (or by killing a weak enemy using contact damage), Charm of the Vampire can heal the player for half a heart while the player is in the process of dying, leaving the player dead with half a Red Heart.
