You can also go into homes in major cities, save right before a chest/cubbord/closet that has MASTER LOCK, and reload till u get a free wonderful sword. Each time you reload a save, it changes anything in the cubord provided it's still locked. I discovered this on accident. It's how I'm able to wear a chest piece with over 800 defesne to anything that required lvl 20 to wear.
