The Chosen Ones

So, after playing more, I have to add what I've discovered:

First of all, my previous post is missing the crucial info - I was playing at normal difficulty. Also, I described Noc'toriah's spell bug very poorly - the problem was not in a strong spell, but in missing animation. Something invisible simply hit me twice and I had no chance to dodge it. I was trying really hard, but couldn't do anything about it...

After that ****** up save (yes, I've learned my lesson ), I played first 5 chapters both on easy and hard difficulty and I had no problems at all. In fact, chapter 1 epic boss was somehow easier at hard difficulty than normal, so something was definitely wrong (which is pretty obvious, considering he suddenly dropped his health from 30k+ to 10k for no reason). On every of these 3 difficulties he sometimes started a spell cast, but nothing happened, which is however already known bug.

I did not encounter the invisible Noc'toriah's spell bug again in either of these difficulties. However, I've discovered pretty interesting bug while fighting the 2nd chapter epic boss - I put the boss into the transformation phase using Fradz' energy ball. The spell didn't finish and the phaze animation started. When it finished, Fradz disappeared completely, including his icon and I was stuck, having to load my previous save.
Edit: I just realised it's also a known bug...

Also, I feel like the steal chances are wrong. Everytime I have 40+% chance, I need like 5 tries, at 20% it feels like trying forever. I might be just unlucky, but I'll probably keep the records of my tries from now, because it feels kinda broken...

Finally, while using both Master's mage staff and Adept's mage staff, you get armor effect only from the Adept's one (or maybe the one that's on higher inventory spot, I forgot to test this). I don't know, if they are supposed to stack, however i feel like you should always get the higher bonus...

I'll keep playing and searching for another bugs...
