How do we unlock the last boss?

[XCOM Junkie]

Just saw in the last notes that there was a last boss, but I don't seem to have access to it. What am I missing?

Nevermind, found it on the wiki. My minion is 2 levels too low!

I'd caught mention in discord of the 35 Infinite First Step. I was only at 10 of those completed previously because I just find constant fast rebirths annoying and didn't want to bother with more than 10 of each of the first three infinite challenges when I did them when they were added to the game. Got done with that grind and then the boss fight was still locked, so I ended up looking on the wiki as well. My minion was 7 levels too low, which took longer than the challenge completions to grind out but at least it was an idle grind that I could leave working overnight. (Left it in the Endavers adventure fight with time warp turned on.)

Yeah, I just threw on the Beastmaster class for the +Adventure Exp and left it with adventure warp on for a while as well. Worked out pretty quick.
