@Zeruvi I strongly believe with smart use of the website unstuck feature and a slightly optimized run this run is beatable. I guess i should beat this time on my own to prove that, might try sometime soon. It's not beatable on Hardcore mode most likely due to the fact that Teldrassil is very awkward without both deathskips and logout skips

No inn logouts definitely is a must, 2 sessions sounds great too, like you said 1-20 in one session is a lot.

What kind of ruleset is there for the 1-20 run? Does it have to be in one session no logout waiting for hearthstone like for 1-10? Or more like the 1-60 run where u can logout and wait?

Please note the run starts 12 minutes into the video, there's a warmup fail at the start.
