Choose a source of water that you can see within range that has a volume of at least 4 pints. Make a melee spell attack against a creature within 30 feet of the source of water. On a hit, the target takes 1d6 slashing damage and, if the creature is Large or smaller, you can force it to make a Strength saving throw, pulling it up to 10 feet towards the source of water on a failure.   The spell’s damage increases by 1d6 and the distance it can pull a target increases by 5 feet when you reach 5th level (2d6 and 15 feet), 11th level (3d6 and 20 feet), and 17th level (4d6 and 25 feet).
