Frustrated with how I never found out what exacly was going on with the Bridge District murders, I started going over what leads I had; eventually I found out about the "Twisted Rune House" in the Bridge District and how to enter it. So I entered. And here's were the strangeness begins...
In the fight against Shangalar the Lich and his lackeys the mage Layene starts summoning a Demon; a Pit Fiend. Okay fair enough, but what happens next is that she goes out of her way to try to KILL the Demon... :S Afaik, Layene herself was the only one in the group that was protected from evil, thus the demon happily strides ahead and begins tearing apart her allies...then SHE kills it. So... eh... what?! Same thing with the Lich in the nearby house; he also summoned a Pit Fiend then immediatly Mazed it... What's up with that? You'd think they'd atleast protect themselves before summoning demons... My party was protected from evil, so it wouldn't have mattered in that sense, anyway. Could this be caused by the "Corrected summoned Demons behavior" tweak from the G3 fixpack?
Anyway. Now that I've killed Shangalar and his lackeys it seems I've effectively ended the Twisted Rune influence in Athkatkla. But I still don't understand what it was about; why was Reijek Hidesman trying to create the Flesh Tunic? What was the purpose of the Skin Dancers? Did anyone actually figure that out?
Thanks for reading!
EDIT
Another question that I can't let go: Why does my Daystar sword do two numbers of damage? It says it does extra damage to evil creatures, and double damage to Undead. So shouldn't that be a flat damage increase, i.e. a single number? Right now it strikes as if it was also doing elemental damage, "Did 20 damage to Lich" then "Did 4 damage to Lich" right under, which means the poor Lich can't get a single spell off and many of these latter battles have been ridicilously easy because of it.
