Only a dozen? Lol. I've been at it over an hour. I've got 2 legendaries from farming the manor going to the fireplace. --- There are 10 kinds of people in the world. Those who understand binary, and those who don't.
TC, I tried for about 45 minutes earlier for the same piece, but no luck. I gave in and just jumped into nightmare instead. Might farm it a tad on this difficulty level instead. If you grow bored of it and want to farm for it while doing something worthwhile, then wait until higher difficulties and everytime you farm the butcher, check the fireplace. :)
Either way, happy hunting fellow hero! --- My backloggery: www.backloggery.com/fadeblom
