Fradz's Set - yeap, in version 2.1c it was tested last time and lagged like I wrote above.
I suppose that the music stopped after the Boss Fight (obelisk) but I've skipped the cinematic.
And got the same thing with mana regen and uber-health regen of Zylcious as it was mentioned above. And also got the problems with dialogues after the fight, and bugs with demon-form - disappiared and not returned.
Btw could you please make Omega Set unstealable? Because you could obtain it only in Ch.10 and it is usable only in non-epic fights in which you actually don't need it (stealed by Zylcious and destroyed by Xvareon).
Btw after the start of Ch.8 heroic achievments were set to 0/7, while in ch.7 I got 3/7.
