Kind of don't get why the Spirits of Harmony are a part of the requires mats for the haunted plans, unless they wanted a soulbound aspect built into it (kind of like how tailors' Imperial Silk is BoP), though in which case, leatherworkers get it the easiest since Magnificent Hides are cheap and are not BoP in addition to not needing Spirits of Harmony for their 522 patterns.

Why do blacksmiths alone have to provide Spirits of Harmony in addition to living steel (which is fairly expensive and not overly abundant as is) for these recipes?
