Star Cannon

Information
The Star Cannon is a very fast-firing weapon that shoots Fallen Stars. The gun does 75 Damage per shot as of the release of Terraria, and uses Fallen Stars as ammunition.

Trivia
The fired Fallen Stars were once retrievable, but due to balancing issues, they are no longer salvagable after fired. To balance the low speed and low power for such a demanding weapon, the drop rate of stars have been increased immensely.

Tips
A good way to farm Fallen Stars for ammo, is making a new world, make a little tower and make a giant flat skybridge. During night time stars will fall onto the bridge, and with Hermes' Boots, you can get them quickly.
