You collapse the stone and earth, creating a massive hole in the ground that swallows all within.

Target a point on the ground within 100m. A hole that is 12m radius instantly appears and all buildings, creatures, plants and other objects on the surface collapse to the bottom of the 16m deep hole. Creatures within 2m of the edge of the circumference of the sinkhole can make a DEX saving throw to try and cling on to the edge of sinkhole and not fall down. The edges of the sinkhole are muddy and smooth, imposing Disadvantage on any skill checks made to climb the walls.
