Cave In

You cause the ceiling to collapse in a 10 foot radius around a point within range. The ceiling must be made of stone or dirt for the spell to work. Creatures in the area must make a Dexterity saving throw or be crushed by the rubble, taking 4d6 bludgeoning damage and be knocked prone and restrained on a failed save, or knocked to the closest spot outside the area on a successful save. Creatures with a burrow speed are not restrained. Creatures that are restrained can escape by making a Strength saving throw or Strength (Athletics) check as an action. Restrained creatures are covered in rubble and cannot breathe, but also have total cover. Creatures outside the rubble can use an action to dig out a creature, making a Strength (Athletics) check with advantage. The area of the collapse is impassible to creatures without a burrow speed until the rubble is removed.
