For obtaining the drop, you have to joke about obtaining it.... It was what happened to me at least...

Aurum Vale, dungeon I only did around 7-8 times in a year because it is the one I MOST HATE. Only doing when strictly necessary. I had my fears it'd be 50 times run for the drop.... So I just refused to go and so... Then I had to go for my lolDRG's animus book... Joked with the party about doing the book + obtaining drop, not even myself believed such a thing could happen, to be honest....Then.... After the dungeon.... Vale Bulbo!

I was just like "D:....." for almost a minute, not believing what just happened, I managed to do a 2 in 1 Aurum Vale, I avoided thousand runs there.... I guess my second dungeon of nightmares (Dz*zfifrnwrnm,a*el darkhold) will be 50 runs as a karma shot.
