Area A circle on the ground with a radius of 2 yards centered on a point you can reach and a cone, 5 yards long, originating from a point you can reach

You raise the top layer of the ground in the circle and hurl it into the cone. The ground in both areas becomes difficult terrain until the rubble is cleared away. Everything in the cone takes 4d6 damage. Each creature in the area takes half the damage with a success on an Agility challenge roll.
