Launch Jumper

The Launch Jumper is a Hardmode Launcher that drops from Skeleton Commandos. Like most launchers, it uses basic Rockets as ammunition, shooting rockets that explode immediately upon enemy or tile contact. Rockets fired by this launcher can hit a single enemy up to three times, cannot destroy blocks, and are rocket-jumpable; that is, being close to the rocket's explosion will propel the player in the opposite direction, dealing 20 damage and briefly inflicting the Singed debuff.

Trivia
