As an action, you cause numbing frost to form on one creature that you can touch or see within 18 meters. The target must make a Fortitude saving throw.
On a failed save, the target takes 1d6 cold damage, and either its speed is reduced by 3 meters until the end of its next turn or it has disadvantage on the next weapon attack roll it makes before the end of its next turn (your choice).
On a successful save, the creature takes half as much damage.
This spell’s damage increases by 1d6 when you reach 5th level (2d6), 9th level (3d6), 13th level (4d6), and 17th level (5d6).
