The Winter's Clutches are an uncommon pair of Gloves that allow the wearer to encrust with frost enemies whenever they deal 
Cold damage.
Likely these originated in Icewind Dale, where tempers run as hot as hearths, and frozen rivers trace the arm of the dale in a network of blue-white tributaries.
