3-level Conjuration
You choose a location you can see and open a 10x10ft maw filled with rows of teeth. Any creatures over the maw as it opens must make a Dex Saving throw vs your spell save DC. Targets take 3D6 slashing damage and are restrained, or take half as much and do not become restrained on a successful save, they then move to the closest space outside of the maw. Creatures that start their turn restrained take 2D6 piercing damage.
