I've looked around in this zone, but all I could find was bwgans... Got a map where the spawn places of Bwgwls are plotted, but I've never seen one ;( Do they look like the bwgans? May it be, that GOA removed them with the last patch?
They can be found right at the top of the map to the north next to the King of the Hill,, between Frenzied Feeders and the Broken Church. I have been soloing these guys for ages to try to get the bowmasters bracer off of them, havn't had any luck yet but I did get a drop that's not listed above,, the Shadowhunters Vest. Not bad item af 50 with 21 hits and 4 Strenght Spec.
