I ran around solo with my choco out and spiritbonding raptorskin gear. I also set my free teleport to the zone I was in. First was La Noscea then Shroud then Thanalan. 5 of the 12 dropped with in the first 3 fates. Longest was West Thanalan. That took 2 hrs. I was much luckier than most. Praise RNGesus!
