I often sell back things I make to merchants to subsidize further advancements. This product was a surprise because I cannot get merchants to buy it even with a 135 Charisma and aly faction with Merchants of Queynos. So, off I go to my merchant bot in the bazaar . . .
Also, this combine seemed to produce a much slower rate of skill ups than others (only one in 12 combines). Could have been just bad luck, but it was strange to get only one point of improvemwnt with 145 wisdom, a geerlok brewing device, and my "Natures Beverages" book opened from an open inventory slot.
