Dark Cone of Cold

This was a dark gift from the Voice of Cold and Hate in Curse of Strahd. There are only 7 charges and then it is gone. 

A blast of cold air erupts from your hands. Each creature in a 60-foot cone must make a Constitution saving throw. A creature takes 8d8 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.
