Empty Bullet

Empty Bullets can be purchased from the Arms Dealer after Hardmode is unlocked. While they have no function as ammunition on their own, Empty Bullets can be used to craft Hardmode bullets with special effects.

Trivia

 * A single Empty Bullet is the cheapest purchasable item in the PC version. In non-PC versions, the only items with a lower cost used to be the Fountains sold- or rather given away- by the Witch Doctor for free until 1.3.0.1.
 * Despite their name, empty bullets are actually cartridge casing. "Cartridge" being the correct term for a bullet, casing, powder, and primer.
