Kingdom Come: Deliverance 2 is rife with sim-y, medieval stuff. You can whet your blades, forge horseshoes, throw some dice, do your laundry, wash yourself in every trough in Czechia, and, of course, do alchemy.
If you're anything like me, that last one is a problem. In my 75 hours in KCD2, I never once managed to produce anything other than a 'weak' potion from my time at the alchemy bench.
Even when I felt like I was following recipes to the letter and the nanosecond, Henry would grumble about screwing it all up when I finished.
Even the perks which explicitly said they'd make the alchemy process more tolerant of errors didn't help. It got to the point that I thought that was the joke—alchemy isn't real, so of course it never works.
But no, I'm just dumb. Or, actually, the game is just really bad at explaining how alchemy works. I've now cracked how alchemy actually works.
