Divine Shackles

Radiant spectral chains wrap around a creature of your choice that you can see within range. The target has to make a Strength saving throw. The target takes 4d8 radiant damage and is restrained on a failed save, or half as much damage and is not restrained on a successful one. A creature restrained by the shackles can use its action to make a Strength saving throw against your spell save DC. On a success, it frees itself. If the target is a Fiend or Undead it makes saves against this spell with disadvantage.
