1. Death port to first campfire. You simply run from the start past the first set of mobs and into the big room. Hug the left wall and die by the wall before reaching the wall on the left and you will end up at the first campfire.
2. Soloing the first boss. Simply run to the back where the round stone is that you click to continue after killing the boss. Run behind the stone and get the boss close to the edge. Now run around the front and either use Oppressive Force as a CW or Flame Strike as a DC. Even though the boss is immune to CCs, these abilities will slightly bump the boss down into the lava. You will have to jump down to get the loot.
2.5 (added after the fact) There is another death port before the second boss. After the first boss you fight a few small adds then a larger room with some miners as well. After this most people skip the giant by staying left and fight those few adds and the next 2 packs. Then there are 2 ways up, on the left and right side to skip some packs and get behind the giants. From here most people will run either to the back wall across the long bridge or jump down in the lava on the right side at the end of the bridge. This will death port you to the next campfire.
3. Second boss a lot of people seem to struggle with. Some of the old places to stand were fixed but at least 3 are still working. You can also suicide this boss and I will try to get some screenshots.
4. After the second boss most people suicide run to the end. There is also a way from the column by the campfire to jump across and over an invisible wall. You can run along the edge and jump over to a platform just before the boss. If you do this you can fight a few of the little kobolds and not have to waste an injury kit.
5. Not sure this one is still working since I haven't felt the need to use it in a long time. Some people know you can jump the wall to the right of the boss entrance. Well you can also have someone pull the boss using this tactic and stand up top to take down the boss without being hit.
Guys let me know if there is interest and I will post a few guides like this for other dungeons.
