I'm sorry if this is old and everybody knew about it, but I couldn't find anything about it in the search. I found a few groups of level 10 Stone Summit in Lornar's Pass. I was with henchmen, and there was a huge group so I was scared and ran, but then I noticed nobody was dying. So I decided to fight, and noticed they were dying in two hits. Then I saw they were level 10-12.
They were mixed in with level 24 Stone Summit, it was really weird. And whereas the level 24s always drop above 100 gold, these dropped about 20.
It was about half way between Dreadnought's Drift and Beacon's Perch, and it was along the route that runners don't normally take, on the east side.
