I think it is clear that some books drop more or less often then others, and in this case, Dark King’s Aura Manual are VERY rare. I've run the 15 stamina maybe 30 times now, the 30 three, and I had 10+ books of each type drop, but DKA - only one. Second hardest in my sample is the Apo book, only 5 or so so far. Does anyone have any numbers for the ratio from 30 stamina run? Are they significantly better? None of my 3 produced a DKA, the one I got is from one of the 15.
