Hum...good questions. I'm too used to playing Pokemon and Hail effects are so underrated (the Ice Type really needs a buff). I was thinking more along the lines of having a storm generate in a very large radius around her (think Jhin W) that scales with certain level breakpoints.

Or you could to the SMITE treatment, where they have their passive effects displayed in a meter icon atop the central HUD. Your idea of having a storm being generated by picking a map quadrant seems very nice.

As for the effect i'd like to see the area of effect work as a ever growing slow culminating into a stun to people inside it, to convey the idea of slowly freezing to death inside a snowstorm.
