Burial

You channel elemental force through a creature you touch. Make a melee spell attack. On a hit, the target takes 8d10 bludgeoning damage. In addition, a creature standing on earth (such as clay, mud, stone, or sand) must succeed on a Dexterity saving throw or be pulled into the ground. Huge or larger creatures automatically succeed on their saving throw to avoid being buried.

A creature that starts its turn entombed in this way cannot breathe. While buried, the creature is blinded, deafened, and restrained. As an action, the creature may attempt to unearth themselves with a Strength (Athletics) check against your spell save DC. On a success, they emerge, prone, in the space they last occupied.
