Thunder Zapper

The Thunder Zapper is a desert-themed Magic weapon obtainable in Pre-Hardmode. It is found in Sandstone Chests in the Underground Desert or Oasis Crates when fishing in the Oasis. When cast, it launches a fast-moving, non-piercing projectile that is unaffected by gravity and will disappear with a visual explosion that does no damage after traveling for about 2 seconds or when hitting a solid tile. The projectile moves up and down in a zig-zag pattern horizontally, but not vertically (traveling straight when shooting directly up or down).

Due to the low mana cost and the speed at which it auto-casts, it can be very useful early on. This weapon is comparable in strength to the Emerald Staff or Diamond Staff.

Trivia

 * Since it is obtainable from fishing, it can be a good early-game magic weapon.
 * The projectile is affected by the zig-zag motion, allowing for some interesting shot placement, but has some slight variability in height change, making it somewhat unreliable.
