Got it on my 27th egg. Farmed religiously for the first few months and stopped playing for a few months as well. Got it on my 4th egg back. The wait sucks but when it finally does pop out of the egg it's well worth it. I sadly missed seeing it looted I had become so accustomed to it not being in there that I was at the NPC clicked it open purchased my next egg and went about what I was doing. Didn't notice that I had got it till about 2 hours later lol. Good luck!
