Lovely idea. I'm all for it, and just wanted to point out that arcane shards do infact drop from the gold orcish chests purchasable for 25 orc tags. Since I have not seen or heard of anyone dropping these in regular maps, I am assuming that these are indeed the elite chests.

Additionally, I would like to see a luck based shortcut to getting the recipes. Perhaps allow a tradable version of them to drop from Elite Rengol maps or the planar arena (scaled to lvl 46 of course, with the addition of some new bosses). Also, as ebezaanek said, instead of using story token, allow us to buy a non tradable version of the recipe with 500 orc tags for 750-1000 planar fragments. Another suggestion on how to get the recipe I would like to make is if STS scaled all old elite maps (from brackenridge) to lvl 46 and introduced a standard elite currency that all bosses drop or have a chance to drop, some number of those could be used as well.
