Blizzard

You cause a blast of frozen wind and ice to hit one creature that you can see within range and. The target must make a Constitution saving throw. On a failed save, the target takes 1d8 cold damage, and it creates a 20 foot area around the target that is considered difficult terrain.

The spell’s damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8).
