Coldfire Vice

You cause a burst of coldfire to restrict the area of one target creature you can see within range. The target must succeed a Constitution saving throw or take 4d6 cold damage and be Restrained until the end of their next turn as the ground and air around them freeze. On a success the target takes half damage and is not restrained.
