G.D.D.

The G.D.D. (or Galactic Dolphin Decimator) is a post-Moon Lord ranged weapon and a direct upgrade to the S.D.M.G. It rapidly fires a stream of very accurate bullets towards the player. Additionally, it has a 50% chance to not consume ammo.

Trivia

 * Its tooltip is a reference to the vanilla item Minishark's tooltip.
