You release a seismic wave, slamming the ground in front of you causing the earth to explode violently in a 30 foot cone in front of you. Creatures touching the ground in the area must make a Strength saving throw. On failure, they take 4d10 bludgeoning damage and fall prone. On success, they take half as much damage and do not fall prone. Large or larger objects and structures in the area of effect automatically fail the save and take double damage. The ground becomes difficult terrain until cleared. Each 5-foot-square portion of the area requires at least 1 minute to clear by hand.
