Energy Rain is an Overdrive, a part of the Swordplay skillset of Tidus. Tidus runs and jumps off an enemy into the air, then charges his weapon with energy and swings it to blast all enemies. Underwater, Tidus just unleashes the beams of energy. Tidus learns this Overdrive after executing 30 Overdrives (cumulative).
