This run was mostly made slower by the fact we were looking for rifts and minidungeons, and the occasional heckling by my audience redeeming screen and control manipulating challenges through Dixper and Streamloots. Feel free to ignore the long timer on the bottom of screen, I was just in the middle of a subathon. Splits are in top left.
Sub 1:30 seems feasible if skipping all minidungeons/rift searches and just doing reset runs on pre-boss dungeons. We didn't actually find a rift the entire run.
Our run strategy consisted of Level 12 for first boss, Level 24 for second boss, then blitzing to the final boss and hoping for level 60 on him.
For this run we tried double Necromancer, which is great on every boss except for the final one, as our minions don't target his chains.
