I wonder how is the spell knowledge gained from reading a book calculated. I've read it depends on your Learning (does it depend on literacy too?) and I've read there's a soft cap after which each reading only give you few points of spell knowledge.
Has anyone done any research about that? What I'd like to know is when the soft cap is reached and how severe is it, i.e. how little spell knowledge you gain after crossing the cap, in comparison to what you'd gain before the cap.
