Create Geyser

You summon the deep waters of the world to explode forth. A 10 foot radius fountain of water explodes forth from a point you can see within range. Each creature within the spell's area must make a Dexterity saving throw. On a failed save, a creature takes 8d6 bludgeoning damage and is briefly launched 80 feet into the air atop a pillar of water. Creatures that fail to reach the maximum height of the geyser take 1d6 bludgeoning damage for every 10 feet they are unable to travel from the force of impact. At the end of your turn, the geyser stops and each creature atop falls to the earth. On a success, the creature is safely ejected outside of the spell's area and takes half as much damage.
