Bloody Tear

The Bloody Tear is a consumable item used to summon a Blood Moon. It can only be used at night; attempting to use it during the day will not commence the Blood Moon and will not consume the item.

It is dropped with a chance by the Wandering Eye Fish, Zombie Merman, Blood Zombie, Drippler, Clown, Blood Eel, and Hemogoblin Shark, and with a  chance by The Groom, The Bride, and Dreadnautilus.

Trivia

 * The tooltip is a reference to , in which the game would show the same text whenever it became night. The name of the item comes from a track in Castlevania II known as "Bloody Tears".
 * This item could be obtained before the player has even fought a Blood Moon. As The Groom and The Bride can spawn in a Graveyard, albeit very rarely, the player could obtain it through some farming.
 * Bloody Tears will only drop if it is night and during a Blood Moon. Thus, any Blood Moon enemies killed after the Blood Moon ends will not drop a Bloody Tear. Also, statue-spawned enemies do not drop Bloody Tears.
