Bloody Tear

The Bloody Tear is a consumable item used to summon a Blood Moon. It can only be used at night, using it during the day will not summon a Blood Moon, nor consume the item. Likewise, the Bloody Tear cannot be used during a Blood Moon.

It is dropped with a  chance from normal Blood Moon enemies, a   chance by the Wandering Eye Fish, Zombie Merman, Blood Eel, and Hemogoblin Shark, a   chance by The Groom and The Bride, and a   /   by Dreadnautilus.

Tips

 * If the player wants a Slap Hand, they can hold on to a Bloody Tear until they find a Skeleton Merchant. They then can use the Bloody Tear, allowing the Skeleton Merchant to sell a Slap Hand.
 * Since a Blood Moon cannot happen at the same time as a New Moon, using the Bloody Tear on a New Moon will cause it to change into a Waxing Crescent. This can be useful for acquiring Phase-dependent content faster.
 * Attempting to use a Bloody Tear during the Frost Moon or Pumpkin Moon will not spawn a Blood Moon, but will still consume the Bloody Tear. If you use the Bloody Tear during a Blood Moon, the tear will not be consumed, and will not change the Blood Moon in any way.

Trivia

 * The tooltip is a reference to Castlevania II: Simon's Quest, 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".
 * 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.
