The element whirlpool

The caster uses a drop of water or any other liquid (other liquids (like acids, poisons, or even lava) can be a small influence to the damage) to conger a whirlpool with a radius of 20 feet from self and 10 ft. vertically. The radius is double if its near (at least 15 ft. away) an accessible water source like a see shore or a river. If its cast while in a river or the see the radius is tripled and the vertical distance is doubled. Every creature within must make a Dexterity saving throw and on a failed save take 3d8 Bludgeoning damage and the used liquid's attributes damage and its amount. On their turn they have to make an a Strength or an a Dexterity saving throw to get out of the whirlpool or move some portion of the way out (determined by their on land movement - 5 ft.)(consumes both movement and an action). Each round that a creature starts in the whirlpool after the first round after getting hit they take the used liquid's attributes damage and its amount (twice as much if its within 10 ft. of  the caster) close t the used liquid's attributes damage. The user doesn't take any damage unless weak to it.
