The Artisan’s Consortium Seal of Approval is a soulbound item that increases your crafting skill by 40 points. I’ve seen them on other characters as a reward for patron work orders, but I have never gotten one on this character. Is this an oversight that they are seemingly unavailable to tailors and enchanters?
You can get them on tailors and enchanters (I have two on my tailor / enchanter) - they are rare. Unlike the other (lower) +skill rewards they are soulbound which is annoying.
