Engerek01: Has anyone been able to find a way for that? I just met Nordom and I dont wanna give up any of my companions. I have grown fond of all of them so far. Annah, Dakkon, Fall from Grace, Ofcourse Morte and even Ignus. They are all very useful as well.
Side question. Has Nordom have any impact on the story like the others? He starts with 36K experience, around 200K below others.
The best way to keep Nordom is to use the PST Tweaks Pack and ensure that the Save Nordom! feature is enabled. Then when you talk to him in the maze, you can get him to wait for you in the main maze chamber, so you can leave, ditch a party member, then go back in and pick him up.
Unfortunately without that mod the only way to get Nordom is to have 5 or less party members when meeting him in the maze. Otherwise he's lost forever. And I'm pretty sure you need to start a new game with that mod (although someone can correct me if I'm wrong on that one).
Nordom does have some impact on the story, albeit not as much as other characters. I think you can get him to tell a story to the chick in the brothel (can't remember for sure), and later on if he's in your party there are a couple of encounters where he has unique dialogue. Also there's some banter between Nordom and others which is pretty funny.
