The Wasp Gun is a magic weapon dropped by Plantera. It is an upgraded version of the Bee Gun, dropped by the Queen Bee. It fires a 2 to 5 Wasps (5 being least likely) with each shot that fly out and lock on to targets. The stingers they shoot will do constant damage to the enemy until it dies. Each wasp will only last a certain amount of time or disappear after bouncing off walls 3 times, and will continue searching for monsters until its time runs out.
- As the Wasp Gun has no knockback, it is impossible to reforge it to prefixes with knockback modifier such as Mythical and Godly. This makes Demonic its best prefix.
- Just like the Bee Gun, the wasps launched from Wasp Gun are destroyed upon touching water or lava, making it useless in liquids.
- Added to the game.
