Create Geyser

You summon water from deep within the earth to explode upward and outward. Chose a point you can see within range. A 10-foot radius surrounding the point explodes outwards and upwards. Each creature within the spell's area must make a dexterity saving throw. If a creature fails, it takes 8d6 bludgeoning damage and is also launched into the air 80 feet via a pillar of water that lasts but a few moments. Each creature then falls to the earth. Creatures that pass the save are safely ejected outside of the spell's area without being thrown into the air and take half of the initial damage.
