I have been playing NWN2 solo for a couple of years now and one of the first things I did was to figure out how to resurrect Amie Fern. She is a Generalist Wizard and great for crafting. She is one of my favorite characters and I keep her right up to the very end of the original campaign. She is not very interactive as she has no dialog after West Harbor. But she does make a very useful member of the party, albeit a mandatory one. I have never seen any references to anyone else keeping her in their party and I was wondering if anyone ever had? I would be happy to explain how if anyone is interested.
I almost always play as a Ranger btw, usually with at least three levels of multi-classing. Really like having the animal companion!
