Black crystalline frost forms over the target. The target must make a Constitution save. On a failed save, the target takes 4d6 cold damage and their speed is reduced by 5 feet. At the beginning of each of its turns, the target makes a Strength saving throw. If it fails, they take 2d6 necrotic damage and their speed is reduced by an additional 5 feet. If their speed is reduced to zero, they are restrained.
If the target makes a successful save against this spell, it immediately ends.
