Cold Gaze

Choose one creature that you can see within 60 feet. That creature make a Constitution saving throw. On a failed save they take 7d8 cold damage. Additionally they begin to make saving throws against petrification. On three fails they are petrified for one hour turning into a statue of ice. (Creatures Immune to Cold Damage are unaffected by this.) On three successes the creature breaks free of the ice and isn't petrified as well as the spell ends. While making the saves the creature is under the affect of the slow spell.  On a successful save against the initial spell attack the creature takes half the cold damage and doesn't have to make any additional saves. Additionally if you loose concentration on the spell the petrification ends early.
