Chain Prison

Choose a point with in range. Phantom chains begin to lash out at all creatures in a 10-foot radius of the targeted point chosen. A creature in the area when you cast the spell must succeed on a Strength saving throw or be restrained until the spell ends and take 1d8 as bludgeoning damage by the phantom chains at the end of each of your turns. A creature restrained by the chains can use its action to make a Strength check against your spell save DC. On a success, it frees itself. When the spell ends, the conjured chains fade away.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d8 for each slot level above 2nd level.
