Minishark

The Minishark is a machine gun that can be bought from the Arms Dealer and uses any form of bullet. It has an incredibly high fire rate, making it devastating against most enemies and is even effective against the first 4 (non-hardmode) Bosses. It has a base power of 6, yielding 13 damage with Musket Balls and 15 damage with either Meteor Shot or Silver Bullets. In addition, each shot from the Minishark has a 1 in 3 chance (~33%) of not consuming any ammunition.

Tips
Skeletron normally takes 4-5 damage from this weapon, but when his head is spinning he loses all of his defense, giving you an opportunity to hit for much higher damage (about 12-16 damage depending on your ammo).
