Coat of Winter
Made from the fur of a winter wolf, this coat provides warmth and protection against cold environments.
You are immune to the effects of natural cold while wearing it, and gain resistance to cold damage.
Short rest, swift, concentration, emanation 2; howling winds whip around you, blowing snow and sleet thick enough to obscure vision. On turn start, the area becomes slippery terrain. Enemies suffer disadvantage to any attack for which a single square of this effect intervenes between them and their target, and they cannot see anything with 2 or more intervening squares. You are immune to both of these effects.
