You strike the ground with your arcane focus and summon a freezing tornado in a 20-foot radius around you. Every creature other than you in the area must make a Constitution saving throw. On a failed save, a target takes 6d6 cold damage and is slowed until the end of your next turn. On a successful save, it takes half as much damage and is not Slowed.                      At Higher Levels.
When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d6 for each slot above 4th.
