The Halflings cant cry about this item either. Thats due to the Stormreapers Boned Shoulderpads, which is the Karana equivalent item, has +6 Dex on it in addition to all the stats this gives us.
If you dig way down into the recipe, the Infused Mithril Boning ingredient starts with a blue diamond -- 1k pp is a bargain for those. Also, you need foraged items from a fairly dangerous and not-well-populated zone (Kithicor). Then, assembling the ingredients requires a master-level (skill 100 or better) artisan in smithing, brewing, and pottery as well as at least a low-level poisonmaker. After all that, you find your local grandmaster tailor with skill well into the 200s to even make an attempt.
I'm not experienced enough to be able to make accurate guesses at high level pricing, but after all that it's gotta be well into the 5-figure plats.
