Percy Jackson and the Olympians: Legends

You conjure a massive wave of water that crashes down on a designated area, creating a torrent that can sweep away foes. Each creature in the area must make a Dexterity saving throw, taking 4d8 bludgeoning damage on a failure and being knocked prone, or half damage on a success, remaining standing. The wave also extinguishes unprotected flames in its area and within 30 feet.
