Worldquake

Choose a point on the ground within range. Creatures of your choice in a 60-ft. radius must make a DEX save, taking 66 (12d10) bludgeoning damage and falling prone on a failed save, or half damage with no prone on a success. Structures in the area take double damage.

This power has its own stable page so it can be linked from any character, item, location, story post, bargain, curse, or future reward.
