EARTH TOMB

Choose a creature (size large or smaller) you can see within 60 feet. The creature must make a DC 8+ STR mod + Proficiency mod Dexterity saving throw. On a failed save, earth pillars shoot up from the ground, encasing the creature. Attacks against the creature have advantage and attacks made by the creature have disadvantage. The creatures speed becomes 0. At the end of each of the creatures turns, it may make a Strength saving throw to escape, breaking the earth pillars in the process. On a successful save, the creature moves 5 feet in an adjacent direction, and the earth pillars take up the creatures original position
