Reading these numbers
At current lowest listed prices the 6 reagents for one craft of Specialized Bio-Optic Killshades cost 1,165 gold46 silver. Most of that is Truegold - 1 at 520 gold each, 520 gold, 44.6% of the whole basket. Watch that one price and you have watched most of this recipe.
Break-even is 1,226 gold80 silver - below that listed price the craft loses gold once Blizzard’s 5% cut is taken. The crafted item has no current Auction House listing to compare it against, so the estimate above is left unknown rather than guessed.
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 →
