There is a screenshot floating around somewhere by a JP linkshell showing Hakutaku having dropped the Peacock Charm. I am wondering if there is any truth to this. Obviously, the picture could have been faked. However, if multiple sources confirm it, it could be real.
The drop rate could just be very bad (nobody believed for a long time that Sozu Rogberry dropped anything but white steel).
So, go do those O-Hat runs and see if this is Fact or Fiction!
