If you want to take two-weapon fighting as a NWP, it'll reduce your penalties by 1 each. So you'll be -1/-3 and get one bonus attack with the offhand weap. Acceptable weapons are limited for your off-hand to be: horseman's mace, horseman's flail, shortsword, horseman's military pick, and dagger (so you'll have to spend a WP also).

Tut2, actually you've gotta do the swap I mentioned below for your stats if you want to dual-class at all. Dual classing requires 17s or 18s in the prime stats.
