Thanks Northernlight412.
I just tried your combo, 12 hours that's shorter than the wizard, night, mismoth, night elf, a bunch of useless commons, etc... that I have been getting.
I hope to breed the Nightshade and complete this tale. I couldnt finish last tale, couldnt get the dragon, even though I boosted, spent gold (bred 7 socials, 5 ambassadors, a few seers/mists/clowns and lots of useless commons).
By the way, my Bingo keeps resetting to the same completed Challenge, cant move on to the next challenge... so many bugs...
