Breath of Night

At your whisper, the chill night wind answers, a forceful gust that heeds your will. A blast of cold air erupts from your hands. Each creature in a 15-foot cone must make a Dexterity saving throw. A creature takes 3d6 cold damage on a failed save, or half as much damage on a successful one. A creature killed by this spell becomes a frozen statue until it thaws.
