Was feeling frisky and decided to attempt to get the Doom Slayer achievement (Defeat the final boss with all demon spawners alive and Badder Bosses challenge enabled).
Been attempting it for a week or so and rarely make it past the 1st boss (I've gotten too used to fighting normal bosses - these challenge bosses keep hanging me up).
Mis-fired a caustic potion at Yog while one of the fists was still up. If I hadn't wasted that potion, I'm pretty sure I would've won this fight.
First time actually making it to the final boss fight with Badder Bosses on, so I feel really accomplished to have made it this close.
Edit:

A week and half a dozen tries later, finally made it!
And with TWO challenges on (ran with Swarm Intelligence on as well).
(Please ignore how much of a one trick pony I am)
Graphics was in DIRE need of an update on original Mount And Blade. Game came out in ~2010, but the graphics felt like they were early 2000's.
Sequel did an 8/10 job on bringing those up to the late 2010's (despite its ~2022 release).
That said, the base game became unwinnable with how impossibly stupid the game AI became. They also tried to build in a "main story" which was busted in multiple fronts and virtually impossible if you ever experienced a party wipe (very common occurrence in the early game).
Even with cheats enabled, my best run at the sequel's primary objective (conquer the map), I only ever got ~25% of the way there after over 200 hours of game play.
