Thorn Cage

Thick vines studded with sharp thorns spring from the ground around a target of your choice within range. The target must succeed on a Strength saving throw or be restrained by the thorny vines until the spell ends. A creature restrained by the vines can use its action to make a Strength check against your spell save DC. Doing so causes the creature to take 2d6 piercing damage from the thorns. On a successful check, it frees itself ending the spell.
