Blue Rocket

Blue Rockets can only be bought from the Party Girl during Hardmode. Once placed, they can be set off by right-clicking on them, resulting in colorful fireworks, much like the other colored rockets. Despite the name, they are not usable with the Rocket Launcher.

Surprisingly, despite not being classified as a weapon, they deal about 150-300 damage on impact. The player cannot be harmed by these explosions.
