Chaotic Shackles

You conjure a set of warbling shackles straight from one of the many planes of chaos, targeting and attempting to ensnare one creature of your choice within range. That creature must make a Dexterity saving throw. On a failed save, the creature is restrained by large, colorful shackles and takes 5d8 damage. The first die you roll determines the damage type dealt for this turn. A restrained creature takes 4d8 damage at the start of each of its turns. The first die you roll determines the damage type dealt for this turn.

A creature that is restrained by the shackles can use its action to make a Strength check against your spell save DC. If it succeeds, it is no longer restrained, and the spell ends.
