Giving Chill something to break

For Chill, I wanted something more physical than another colored cloud. Small crystals growing out of the feature felt like a good fit. They give the frozen upgrade a shape you can recognize while the ball is elsewhere.

Getting that idle right took a few passes. Some crystals were appearing and breaking before the growth was really visible. They now have a proper growth phase, sit on the surface with a little pale mist, and cycle while the effect is available.

When a hit actually awards Chill, the visible clusters shatter together with extra ice fragments and mist. The hit doesn't have to wait for a new crystal to grow first. If there aren't any visible crystals at that moment, it still gets an impact burst. I like that the ready state gives the hit something to visibly use up.
