I think the one in the Hinterlands is 15. Don't let that fool you, though. My party is high enough that he's not GIANT SKULL OF DOOM-leveled, but he still rips them to bloody ribbons. Or, well .. nearly. I'd stand a better chance if the party AI wasn't useless.
Not a single meaningful dialog in quests since my last post here, what, two hours ago? I managed to finish a quest leading to an exciting-looking cave, and what'd that get me? A collectible item, some armor that was barely any better than what I had, and a few cave mushrooms. Yay!
