The Caustic Tear is a Pre-Hardmode item used to summon the Acid Rain event. A non-consumable version can also be crafted. Using this non-consumable variant while the Acid Rain is currently active will prematurely end the event.
The consumable variant can also be purchased from the Sea King for 3 after any tier of the Acid Rain has been defeated.
