I've been skimming through the dialogue for Azif and saw this:
"One of the things I found quite surprising in your tale, though - beside the things he spoke about - is that you dared attack him and lived to tell the tale. It is fascinating, though of lesser importance now... "
Implying a contingency for attacking Six and not getting merked. To my knowledge, there's only three places where this can happen:
1. Lower floor of Oculus while he's still there (although attacking him there would make the oculites hostile and render the dialogue moot),
2. West wing of the institute, where he can be attacked without outside retaliation (I guess you could take a potshot at him and leave the area?),
3. Entrance to Hollow Earth in Deep Caverns (Ditto, though I imagine it makes getting the mykocardia way harder).
Obviously there's no way to kill him since he's immune to all damage types (I tried Hoddurform and the Ethereal Torch for shadow/light damage, neither effective), but has anyone ever triggered this dialogue?
