The rail gun is a very special weapon dropped by the Mecha and ÜberMecha it takes no ammo, but instead 10 mana a shot. It shoots a 40 block long thin laser than can pierce through unlimited blocks and unlimited monsters. It does 30 damage, and can only be shot every 2 seconds. It is the weaker version of the Zammer and the Hallowed Rifler. It can only be shot left and right, making it hard to use against flying enemies.
