1) Arronax didn't recommend I get help from the other banishees in the void. I thought he's supposed to? 2) I thought the guards in Kerghan's castle are supposed to let me through when I don't have Arronax with me? 3) I thought I heard somewhere Z'an gets turned to stone. Didn't happen? 4) When I convinced Keghan he's dumb I'm suppose to be able to use the device on him but I still had to fight. What's up with that?
1) He does so once he joins you if I remember correctly. 2) Arronax or not they are hostile. The only non-hostile guards are the ones in front of Arronax's cell. 3) Don't know about that. 4) Perhaps a bug. Then again I never convinced him he's wrong I'm not sure.
1) It depends on how strong your party is. If your followers are weak, Arronax recommends replacing them. 2) I believe they only let you in if you didn't release Arronax from his shell. 3) She occasionally uses the Earth Elemental spell on herself in combat. 4) You still have to weaken him to use the Vendigroth device. The battle is much shorter than normal, and I don't believe he fights back. Semi-related question: Has anyone been able to get any of the four 'god of Arcanum' endings to work? Whenever I try, it says I returned to Arcanum with Kerghan (which is incorrect, since I *killed* him). For anyone who's unfamiliar with these endings, you have to agree to join Kerghan, but then change your mind and say you will rule Arcanum alone (as a good god, evil god, non-interfering god, or unsure what kind of god). -Poiuyt Man
