Arduen's Telekinetic Hammer

Create a 15ft diameter and 40ft tall cylindrical hammer that strikes a point you can see within range. All creatures within the spell effects area are hit by it when the spell is cast. When struck by the hammer a creature must make a strength saving throw. A target takes 6d10 force damage and is knocked prone, or takes half as much damage on a successful save. The area where the hammer landed counts as difficult terrain.

On the players turn they may use their action to bring the hammer down on another point within the spells range.

If a creature is flying, or above the ground holding onto a stationary object and fails their save they fall to the ground prone and take an additional 5 points bludgeoning damage on top of the standard fall damage.

If the spell is used at a higher level, add 1d10 per lvl cast.
