Apparently Magnus doesn't want to join me, is there something wrong with what Quest I had done before I get my hands on the necromancer jewelers? Or does my character build matters? If the latter does, my char is a Female Half-elf with Chartalan's Protege background, currently expert in Persuation. And my current followers are Virgil, Sogg, and Dog. I'm currently at Level 5. I know I have to search for some old threads regarding Magnus, but for some reason I just couldn't find the answer that I am looking for so I just post this anyway. Thank you very much for those Lords who could help me I'm glad to be back playing Arcanum since I stopped playing it for grad school in 2010.
It could be that your level is too low (his starting level is 8 I think), or that you have evil alignment. I would imagine with being a persuasion expert you'd have the charisma to support another follower, max followers can be found the character sheet.
