Cold Snap

You create a momentary area of extreme cold around you. Each creature within range, other than you, must succeed on a Constitution saving throw or take 1d6 cold damage, and its speed is reduced by 10 feet until the start of your next turn.

This spell's cold damage is increased by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
