Some new Unique Chaos items do not function like regular unique items. For example, ‘‘Mantle of Mountain’s Fury (Chaos)’’ and ‘‘Tuskhelm of Joritz the Mighty (Chaos)’’ currently do not work as intended.
Mantle of Mountain’s Fury (Chaos) stops working if you use any item that contains the ‘‘Aspect of Ancestral Force’’ - https://youtu.be/K8OUCE3-kWo
Tuskhelm of Joritz the Mighty (Chaos) provides no bonuses while in Berserking state, even if you have multiple sources granting Berserking - https://youtu.be/Ew3l2O3q8EQ
