Around -1700, 700 there is a cluster of splorgaths just outside a tunnel. They all roam around an underwater room, including the named. None see invis. Best way to fight them is to invis past them into the tunnel and pull them up into the tunnel, which is dry land. Hits for about 1500 and stuns a lot, but nothing other than that. Not too hard. We encountered it while doing the scavenger hunt quest. Were fighting in the tunnel I mentioned and it was up behind us, so mage used lvl 52 pet to pull it up into the tunnel solo. Dropped the earring. Guildies got a good laugh at the link, since the original earring is -20 to all resists and no stats lol.
