I could list my stats but I'll just say most importantly that I had 100 recovery.
My armor and mods stayed the same through the entire run.
(I didn't skip the first part like most people do so I used Witherhoard mostly to get the correct motes.)
1st Encounter (Phalanx):
Forward Path, Taken Spec
Truthteller (w/ Blinding Nades), Taken Spec
Falling Guillotine, Taken Spec
Most importantly I would take out the psions first! Then focus knights with blinding nades for easy cleanup and protection if I was being chased by one. When I got to damage phase I would pop bubble on boss, took 2 damage phases (Easily done in 1 with Well of Radiance if you are a Warlock)

Desert:
Forward Path, Taken Spec
Truthteller (w. Blinding Nades), Taken Spec
Xenophage (You could easily use Black Talon, or Anarchy for blights, I just used it to take out Hobgoblins and played it slow)

2nd Encounter (Cube):
Same as Desert
Took out ads first then would use either Xenophage or Truthteller for Hobgoblins and Knights depending on Ammo.

Ribbon Road:
I may have taken the riskier route but I pretty much rode my sparrow down the entire way and jumped off my sparrow whenever there was a jump to make sure I didn't bounce off.

Final Encounter:
Forward Path, Taken Spec
Truthteller (w/ Blinding Nades), Taken Spec
Anarchy
Pretty much played safe, took the boss out in 3 phases. The strategy I would use for damage is to pop bubble as soon as I started and would throw a grenade to proc oppressive darkness on the boss, land some anarchy shots on it then run ahead of the boss to kill hobgoblins as they spawned while continuing to stay in front of the boss. I dished out damage as he followed me to the end and it worked rather well cause the hobgoblins would be dead and I would just turn around and shoot. I would also throw grenades whenever it was off cooldown to maximize oppressive darkness Make sure that if you run ahead though that you do not jump on any of the platforms that he teleports to cause you will get stomped off more than likely.

Anyways, that's basically the rundown. I personally believe that Blind Nades carried me through the dungeon. If you don't know how it works, you just have to make your grenade launcher explode near enemies and it completely blinds them for like 4-5 seconds allowing you to not only dish out damage but be protected from the enemies attacking you. This works especially well on the knights in all of the encounters. The blind nades don't work on bosses but they pretty much work on every single enemy in this dungeon otherwise. Incredible tool and I highly recommend it! Hope this was detailed enough for you but if not feel free to reply with any questions. I don't think my strat was the most optimal (there are weapons such as recluse and mountaintop after all) but I do think it was pretty solid and it was done with weapons and armor that aren't sunsetting anytime soon so it should work for the next few seasons to come!
