Slingshot frames

[Mysterious box]

So a thought I just had was that the scrappy frames should increase the effectiveness of the special effect rounds if you charge them for example a charged freeze round would would be considered 4 shots of a ice staff, slowdown rounds would be considered 2 shots of a slowdown round, and cursed rounds would 100% trigger the shadow tentacle if fully charged and prehaps it would be a bit larger, and gunpowder rounds would have a increased chance to crit just to add a bit more uniqueness to charged shots.
