Tidal Whip

You create a solid whip of seawater that lashes out at your command toward a creature in range. Make a melee spell attack against the target. If the attack hits, the creature takes 4d4 bludgeoning damage. Additionally, if the creature is Large or smaller, it must succeed on a Dexterity saving throw or be knocked prone and pulled up to 10 feet closer to you.

When you cast this spell using a spell slot of 3rd level or higher, you create one additional whip for each slot above 2nd.
