Bull Stomp

You create a seismic disturbance and an intense tremor rips through the ground in a 20-foot-radius circle centered on the point you smash your hammer.

The ground in the area becomes difficult terrain. Each creature in the radius of the spell must make a dexterity saving throw, on a failure the creature falls prone and takes 4d6 bludgeoning damage. On a success the creature takes half damage.
