Devouring Shadows

You call upon shadow itself to consume a target you can see. The target must make a wisdom saving throw (spell save DC)

On a failure the target is trapped within the shadows and has the restrained and blinded condition. Magical and non magical light cannot penetrate the shadows. The target takes 8d8 psychic damage. The target must reroll the save at the beginning of their turns to escape. On failure the target takes the damage again.
