Does 2 days since the previous post still count as a double Post? You do't have to vault anywhere. After the Hobknobbing quest, you can go back a little later and the big gate will open to where you saw the hobbes doing their little sing-a-long. To the left of that area is the stream. You can swim to the right through a bit of maze to find a chest, a dig spot (I think) and their will be a key there too. then go back and venture to the other end of the stream. you'll have to kill a few more hobbes but you'll soon reach the key you can see nearer to the cave entrance, and will be another chest and a few more dig spots too.Hi I'm trying to get my last 2 silver keys and they are in dank water i finished the quest but i cant seem to jump into the water do i have to vault somewhere or what I've been at this for about 2 hours.
