Space gun

The Space Gun is created with 30 meteorite bars, a flintlock pistol, and 10 fallen stars. It does 16 damage (since update 1.0.5) and uses 9 mana per shot. But if you have full meteorite armor on, the mana per shot is reduced to 0 so you can fire it as much as you want. It shoots green lasers that will go through an infinite number of enemies.
