The spell caused a square portion of the ground to erupt in a fountain of earth and stone that occupied a cube 20 feet (6.1 meters) on a side, hitting all creatures within that volume that could not evade the effect in time. The violence of the spell increased with the caster's power. Although the fountain only lasted for a moment, it covered the area in debris that required a long time to clear.
