Thruun's Charged Chains

5 lines of lightning appear from different directions and descend on the target, wrapping around it like ropes. The target must make a dex save against your spell save dc or take 5d12 lightning damage initially and is restrained by the lightning rope taking 1d12 lightning damage at the end of each of its turns. On a successful save the target takes half damage and is not restrained not taking any recursive damage. The target can make a strength check to escape as an action.
