This remarkable ring is part of the set Bratgrimace's Legacy and earlier would not appear in the chest for the respective download. I checked and the piece appears when using the CM Patch 160. However, this chest houses twelve rings for each designated level. Also, the modifiers are much more powerful than those that are delivered with the other set pieces. Let the people rejoice!
