And if You put an enchanting (or whatever it is writed) way for swords how sell it to an Wizard and make him enchant the weapon then he will deliver you the weapon and this ... enchanting phase will upgrade the buy cost . :D
I Think you can add some exp for this game but not the normal exp how : if you get 30 you recieve 30% of speed in forge. i mean that with the exp you make better the swords or hammers or whatever it is. :D
