You create a wave of water that rushes in a 30-foot line that is 10 feet wide from a point you can see within range. Each creature in the line must make a Strength saving throw. On a failed save, a creature takes 8d8 bludgeoning damage, is pushed up to 15 feet in a direction following the line, and knocked prone. On a successful save, a creature takes half the damage and isn’t pushed or knocked prone.    If you cast this spell on a point of freestanding water that is at least 20 feet deep, the line is 60 feet long instead, and any waterborne vehicle in the line has a 30 percent chance of capsizing if it is Large or smaller and a 15 percent chance of capsizing if it is Huge.
