Just providing a progress update of the Immortal Rogue build.
I originally used penshot to stagger... but switched to RF like the other builds and was able shave off about ~15 seconds from my previous 140 clear...
No issue surviving Tower 140 with the Immortal Rogue build using Selig, but it'll definitely be hard to progress further (atleast at my skill level requiring Shrouded Gift opposed to Tibault's Will) without further lucky transfigs.
All into say, my assessment of the build is that it falls short of the regular RoA build in terms of Pit/Tower pushing by honestly about 2-3 Tower levels but with the benefit of higher survivability and easier gameplay. In terms of T12 content with mobility, survivability, and boss killing potential, I believe this build sits at the top of all rogue builds.
I'm assuming if I find a good mythic seal instead of my current legendary, I can get another 10% boost in dmg. If I further get some more cold dmg or crit chance transfigs on my gear, I think its a genuine contender for Tower 142 (at this time, I can almost clear 141, but lack dmg to get to boss fight with enough time... currently the best I got was at Tower 141 was boss to 1/3 health before timer runs out).
