Eruption

You stamp your foot, causing the ground to fling upwards and form jagged spikes of rock in a 20-foot-radius circle centered 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 x 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.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d8 for each slot level above 5th. In addition, the distance a creature is thrown increases to 2d8 x 10 feet (6th level), 2d10 x 10 feet (7th level), 2d12 x 10 feet (8th level), or 2d20 x 10 feet (9th level).
