Hmm I tried
breaking the mirror prior to killing her and got some kind of nasty curse. I wonder if doing the same thing after she was dead would be different?
Hmm, will have to try to break it now that she is dead. As for the ones wearing the mask, I killed all but 2 of them, the other 2 i was able to knock unconscious, but when I got back only one was alive after hag was dead and rested.
