- Evidence: 21 current listings holding 1,303 units of the crafted item in the US region. We see listings, not sales, so how many sell and at what price is unknown.
- Outlier: the crafted item’s lowest listing is 88% below its 30-day median of 8 gold25 silver, so this estimate rests on a listing far below its usual level.
- Items per craft: the game’s spell data creates 10 per craft, so the listed value of one craft is that many times the lowest listed price.

Reading these numbers
At current lowest listed prices the 1 reagent for one craft of Cobalt Skeleton Key cost 59 gold.
Break-even is 62 gold10 silver per craft, 6 gold21 silver per item at 10 items a craft - below that listed price the craft loses gold once Blizzard’s 5% cut is taken. The crafted item’s lowest listed price is 1 gold, which does not clear it.
The crafted item currently lists for less than its reagents cost: −49 gold before fees, and the Auction House would still take 50 silver of a sale, so a craft loses 49 gold50 silver at these prices. At current listings, buying the crafted item costs less than making it. That is an estimated -83.9% return on the gold you put into reagents.
Listing depth right now: 1,303 units across 21 auctions region-wide. Depth separates a market price from a single asking figure, but listings are not sales, so read it alongside the estimate.
Costs use each reagent’s lowest listed price; the estimate is the crafted item’s lowest listed price, times the items one craft makes, minus those reagents and Blizzard’s 5% sale cut. Listings are asking prices, not sales. Recalculated every snapshot and left blank rather than guessed when a price is missing. How we estimate crafting profit →
