I cant seem to even find the cave that any of the guides Ive looked at is talking about. They all say in a cave in the channel that runs around the city around black isle but I sure cant seem to find any cave other than the one with the sea monster skeleton in it. Any help would be appreciated. Maybe Im just overlooking it altogether.
EDIT: Nevermind Im an idiot. I found it and realized Ive been here before.
