Through the quest that you are meant to trigger at levels 8-11. (That Thing at Haven. You know, the Thing. With the people. And the stuff.) We were level 10, but at least for us I don't think it was enough. We've gone back to grind a bit, close out some areas we rushed past last time. I think we're 15 hours? Since I didn't finish the Thing, please no spoilers in comments for the Thing, or for after the Thing.
