Normally, when creating an item there is an XP cost; however, I do not like taking away experience from players. Not only that, but you are in effect losing knowledge in order to create something. This being the case, I am taking away the XP cost for crafting items. In it's place (since I do not want to give you something without taking something else away) any items crafted that would normally require an XP cost will instead have their gold requirement increased in by a scaling amount:
For every 10 XP that it would cost to create the item, it will instead increase the cost by 1%, up to a maximum of 150%.
example: An item that would normally require 1000 gold and 100 XP will instead cost an additional 10% gold, bringing the total cost to 1100 gold.
