Practice Makes Perfect (Open)
Cait was practicing with her powers out on the lake. She stood on the surface of the lake and moved water all around her. Columns shot up into the air to crash back down, whips shot out and struck targets on the shore, tall waves rose from the surface only to disappear as quickly as they formed and small spheres rose from the surface before turning into ice daggers and went flying at the targets on the shore.

In her book there was no such thing as too much practice.
