Twisted Corridors seem to be much harder than normal Torghast, which is why I think a new thread is justified.
Today I tried it for the first time as ilvl 203 WW and made it to 3/17. I had bad luck with my HP which maxed out at only 62k and some mini boss mobs were hitting for 30-40k. On the 17th floor towards the end I found an anima power which I haven't seen before: a single hit can't take away more than 25% HP. This helped a lot, but I already had that Taragrue guy following me and he reached me while fighting the boss. That was the end then.
Up to 3/15 or 3/16 everything was relatively easy, but then changed on 3/17. I was mainly killing with stacking damage with 4x BK into fist, which was hitting for 100k or more with the first tick. Leg sweep and ToD were without CD at this point. Kiting with super jump also helped sometimes, to gain time for stun DR.
I also had a few stupid deaths like falling off of those chains or trying to walk through insta-kill-fire because the mechanic to avoid seemed to be too annoying to try. Who would guess that some little flames can insta kill you?
So, what worked for your WW and how far did you get?
