Maybe something you picked up recently? Or something you found that was a game-changer.
Personally, I’m doing 5(HC, BB, OD, SI, FR) challenge runs with okay success and am looking to upgrade to 6.
The skill jump to add one challenge is very large, especially from adding Darkness or Pharma. Game changer would be understanding vision and how mobs see you.
For me it’s just win consistency with all classes. For Pharmacophobia, it’s not so bad with Warden or Warlock. Rogue and Monk can mitigate Faith is my Armor. Into Darkness is annoying, but I think I can get used to it like the other challenges I normally take.
Supernewb52’s guide, and 9chal speedrun, was a breakthrough for me. I did win before, but it was what really started me getting good. So far I’ve ascended 6chal a couple times and am running 7chal atm.
