Edeneth's Seismic Upheaval

You hurl a sphere of earth-shaking power into the ground which dredges a shallow fissure through it before shooting up at the target. Make a ranged spell attack. On a hit, the target takes 5d8 points of force damage and makes a Dexterity saving throw, taking 1d10 bludgeoning damage and is knocked prone on a failure.

Hit or miss, the ground within a 30ft radius of the target is difficult terrain and requires an action to clear 5ft of it.

At Higher Levels: casting with a spell slot of 6th Level deals an additional 2d8 Force damage 1d10 bludgeoning damage on a failed saving throw. A spell slot of 8th level adds an additional 2d8 Force damage and 1d10 Bludgeoning.
