@Hookshot: So am I if it wasn't obvious. Prediction based on physical movement, large room for error that could be reduced over time with user's experience. Leak, I originally though of an alcohol producing semblance with fire dust interaction but I thought lets make it a bit more effective. Aura as a more effective catalyst or catalyst enhancer was kinda the idea, but as Ray and even me said, too wide a range of applications to be feasible really.

@Someone: Elemental conversion sounds like a cool idea but could be too different from my suggestion. Can make it yourself if you prefer, or I could, what ever you want.
