Found a pair of these on the Cargo Clockwork that roams outside Ak'anon entrance. Camped the guy for the better part of four levels and only saw the one pair.
Found these in Cazic Thule while killing some lizzies, I have killed or participated in the slaying of more than 200 lizzies and this is first pair I've seen there.
A couple of these dropped off the Golras on the iceberg. I would say they are a very rare drop, got 2 after killing over 100 golras...but it could just be my bad luck.
I found these on a saltwater croc in Ancient Croc room (loc: pos 1647, pos 547) in Upper guk. No idea what they are used for. The spell "identify" doesn't give any info either. (12/23/00)
