Go in thru Baron's side, hug the left, and walk into living side. While you're under the "joining gate" do a /tar Hearth to see if Hearthsinger Foresten, HF for short, is around. He has 4-6 different spawn points, not exactly sure on all of them, but it's and e z kill and he drops a blue and a Corrupter's if u have ur AD trink equipped. You can hug the wall passed all the mobs and weave your way to a narrow alley with a gate on the right side. The Unforgiven spawns here, another blue and a Corrupter's. Hug the right some more, if HF wasn't near the "joining gate" he may be around here, so do a /tar Hearth. Hug the wall some more and you should be at the Scarlet Bastion area. From here, you have to see how well you can handle the Scarlets. Hope this helps a bit. I do this on my 70 warrior. I haven't tried soloing the Scarlets tho.
