All eight pieces of epic jewelry of Interlude: which epic raid boss drops each, with what chance, its grade and the bonuses it gives.
As you all probably understand, epic jewelry is not crafted (and one would so like it to be) but drops from epic raid bosses. It differs from ordinary jewelry in that it additionally gives a heap of strengthening stats. I want to answer at once a question that is asked very often: in Interlude epic jewelry does not additionally strengthen the landing of debuffs on an opponent. That is, if the stats include 50% protection from poison, your poisoning spell will not get 50% stronger; such additions were introduced in later chronicles. And of course the Koreans insured themselves against cunning players: if you are equipped with two identical epic items, all the additional stats will be counted from one piece only.
