You are now able to sell/trade/buy more esoteric and conceptual goods. Whether they be powers, lifespan, souls, health, magic and more. As long as the one trading away the goods is the owner of said good. For you however, most of what you sell will still resupply. So any powers of your own that you sell/trade will stay with you, and your customer shall receive a copy just as good, or as outlined in the deal. (1 of a kind goods, such as souls will not be resupplied.) Both parties must agree to the deal/contract with complete free will. Your ability to accurately gleam the market price of any item as also increased. Now able to gleam the price of any goods you are able to buy/trade/sell.
