Scape/Gemspark Blaster

The Gemspark Blaster is an early pre hardmode ranged gun, it's fairly easy to get, only requiring you to get an arms dealer and grab a couple diamonds, and It's firerate is quite high for a weapon so easily obtainable. It is a great earlygame pick, and can possibly take you all the way to skeletron. It is also the counterpart to the Shinespark Sharpshooter.

Trivia

 * The weapon originated from one of Protechol's mods, 'FractalaMod' and the weapon was a multitude of gems, and not just diamonds and platinum.
