Description
You stamp your foot, causing the ground to fling upwards and form jagged spikes of rock in a 20-foot-radius circle centred on a point on a stone or earthen surface you can see within range. That area becomes difficult terrain, and each creature in the area must make a Strength saving throw.
On a failure, a creature takes 4d8 piercing damage and is thrown 2d6 * 10 feet directly away from the surface (which can include vertically). On a success, a creature takes half as much damage and isn't thrown. Creatures that are Huge or larger have advantage on this saving throw. Each 5-foot-diameter portion of the difficult terrain requires at least 1 minute to clear by hand.
