Personal thought here but I think it would be a grate help if you could either dismantle enhancement prisms to receive something 3/5 enhancement cores or possibly allow a vendor to buy them from.you in trade form eg a prism for 3/5 cores. Reason i suggest this is because im currently sat with 20 prisms and no cores but i n eeded 5 cores to masterwork my palindrome. I found myself deleting my saved legenderies in order to try get cores from them because I dont have enough legendary sharda to buy a few cores from spider. I think it could make a nice addition to the vendor system.
