A blast of crackling cold air erupts from your hands. Each creature in a 60 foot cube must make a con. save. On a failed save creature takes 8d8 cold damage or half as much on a successful one. They also take 1d12 lightning damage. You may spend 2 sorcery points to deal 1d12 damage automatically for 1 minute. A creature killed this way becomes a frozen status until it thaws.
