This is a gun. It should either be a boss reward from a devilite boss or a sort of rare prize box drop from treasure boxes in devilite levels.
Maybe instead of a new boss it could be for grim sparks?
This weapon starts at 2 stars.
The clip holds 4 shots of presurised air. These should be as fast and large as valiance shots.
It can be crafted into either a pure normal, normal/poison, pure shadow, or shadow/fire.
The charge attack produces a twister as tall as a extra tall player. This twister will have a low damage but high hit rate allowing it to make enimies trip easily. It has no hit cap, is grounded(breaks when hits wall or a ledge), travels at most 7 blocks, and the hit box to break the twister is smallerthen the damage area so this means it can break blocks easily, the twister should travel as fast as a pulsar shot.
This sounds like something I'd want in game. I also like the idea of using the Grim Sparks to get the gun as the only purpose those sparks have is a 10k crown boost at 100 sparks or just a random mat. There should be a weapon/armor for getting enough Primal/Forge Sparks too, maybe at 150 or 200 tokens?
