By starting to train sword skill now with lots of battles.
Anyway, I know for a fact that some of our nobles in Thalmarkin are still training skills... I don't think it's ideal but they're doing it with their own gold and it's no business of mine as long as they're useful to the realm. The days of "counting coppers" are over.
Roughly a third of Thalmarkans are Heroes whose sword skills translate to increased CS (Theoretically).
