Magical ice quickly spreads from a point you touch, extending in a line 60 feet long and 20 feet wide. Each creature caught in the ice’s path must make a Dexterity saving throw. On a failed save, a creature takes 5d8 cold damage and is restrained by ice. On a successful save, a creature takes half the damage and isn’t restrained. The line then becomes difficult terrain for 10 minutes. A creature restrained by the ice must make a Constitution saving throw at the start of each of its turns, taking 1d8 cold damage on a failed save.    A creature restrained by the ice can use its action to make a Strength check against your spell save DC. If it succeeds, it is no longer restrained. If a creature remains restrained by the ice for three of its turns, it becomes petrified at the start of its fourth turn, turning into an ice sculpture.
