How do I finish wayfarer hills
stand next to the entrance for a few seconds without going in (at least that’s how I did it most recently)
go in the spider cave under cragstead, just a bit north from cragsteads entrance
I’ve gotten it by going to where the nearby portal is, then going west through the pathway, along the cliff edge to the north. I’ve been able to trigger it by scraping the side, along that path.
Like Flubble said: From the waypoint go east into the cave. There should be both the POI and the Skill challenge.
