What does the existing trade skill do?
*oh never mind. I just found it. Well I was thinking more about if your trading skill is high enough, you can even get things cheaper even though a lord of a region sets the price to lets say 50 gold per 100 metal pieces.
Like a trader with trading skill of under 20 won't get anything discounted but over 20 under 40 can get things for maybe 5-10% off? 40 - 60 = 10-15%, 60 - 80 = 15-20%, over 80 = 20-30%?
or get more out of it instead of getting discount.
