sonicimpala asks: What is Vax's highest stealth roll? I seem to remember around 42 but I'm not sure.
He rolled a 43 in Episode 31, Part 2 (0:26:08). That’s a Natural 20, plus his Dexterity modifier, plus his Proficiency bonus twice for Expertise, plus 10 for Pass Without a Trace. This was back when he still had advantage on all stealth checks from his cloak, but on this particular roll, he rolled the Nat20 on his first attempt!
