Am I missing something? I keep getting more of these than I can really use, but unlike other forms of currency, I can't seem to exchange it for something more useful (e.g. even trading them for scrolls of wisdom or portals). I believe Yeena will only offer me a wisdom scrap for one.
Am I just supposed to hoarde them or give them away? (Sure, I use one or two on a map every now and then, but I find more than I use.)
Is it intentional that I cannot really exchange these at vendors, or am I missing something? It would be nice if we could exchange them for something simple, like Alterations, Transmutations, or even Scrolls.
