It turns out I missed so much interesting stuff!
I would have made Nastya a Warrior too. I collected 3 (or so) sets of artifacts for her, but I couldn't equip them all because she was a Sorceress, and at least one item in each set was designed for Strength. There was an elven cloak, Craig Heck's armor, and something else. I think it was some kind of boots.
And what is "Divine Absence"? I still didn't get that achievement. I only got the one for completing the Necropolis campaign.
