Wrap

You summon an otherworldly creature to wrap around your target. Choose a creature you can see within range. That creature must make a dexterity saving throw. On a failed save, the otherworldly creature wraps around the target, grappling them. At the end of your turn, if the target is still grappled, the creature constricts, dealing 1d6 + (spell attack) damage. At the end of a target's turn, they may make a strength saving throw to break free of the grapple. 

At Higher Levels. The spell’s damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
