So say there is a loot drop of a +1 Longsword. And I get lucky enough to get the longsword. Well by this point I have enough gold saved up I wanna increase the magical enhancement. So I go to the Blacksmith or whomever does these things and I ask for it.
Do I have to play 8000 Gold to buy the +2 Enhancement or do I need to pay the difference in price between +1 and +2 which is 6000 Gold?
The distinction is if someone is using crafting to increase your enhancement bonus then you just pay the difference. If you are having to buy one (and thus sell off your old one) then you pay full price.
