Cold Snap

The temperature at a point within range suddenly drops to absolute zero.

Each creature in a 20-foot-radius sphere centered on that point must make a Strength saving throw. A target takes 6d6 cold damage on a failed save, or half as much damage on a successful one. If the target rolls a 5 or less, they become petrified until the start of your next turn.

While petrified this way, they creature's weight does not increase, is immune to cold damage. The petrification ends if the creature takes fire, bludgeoning, slashing, or piercing damage.
