Divine Chain

You bring forth a chain of divine energy that erupts from the ground in an unoccupied space of your choice that you can see within range. When you cast this spell, you can direct the chain to lash out at a creature within 30 feet of it that you can see. That creature must succeed on a Dexterity saving throw or be restrained until the spell ends. A creature that starts its turn restrained by the chain takes 3d6 fire damage.

A creature restrained by the chain can use its action to make a Strength or Dexterity check (its choice) against your spell save DC. On a success, it frees itself.
