Winter Rings are Rare rings that have 3 random secondary stats, and one of the following primary stats: attack damage, ability power, armor, magic resist, or health.
Unlike many other rings, Winter Rings cannot roll speed as a primary stat.
Winter Rings are given as a Card Reward from the holiday multiplayer mission, No More Bad Toys!. The rings are a pretty common reward from the multiplayer mission, and should not prove tough to get.
