You create a momentary circle of spectral ice blades that sweep around you. All creatures within 5 feet of you must succeed on a Dexterity saving throw or take 1d6 cold damage. On a successful save, they take half as much damage.

This spell’s damage increases by 1d6 when you reach 3th level (2d6), 6th level (3d6), 9th level (4d6), and 12th level (5d6).
