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 in Oasis Crates obtained from 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 one second or when hitting a solid block. The projectile moves up and down in a randomized zig-zag pattern horizontally, but not vertically (traveling straight when shooting directly up or down).

Tips

 * Due to the medium mana cost and the very fast speed at which it auto-casts, it can be seen as an alternative to the gem staves. However, due to its lack of piercing and the fact its is lower than the higher tier staves, it is generally an inferior option against slow, bulky enemies, while its fast and autofiring projectiles can give it an edge over faster enemies or bosses.
 * The zig-zag motion of the projectile facilitates some unusual trajectories, e.g. through a half-tile gap.
