in pf2 you can’t.

I run pf2e and love it, but I really gotta call this out as bullshit. It's actually one of the worst things new people can read about the game, imho. I read this a lot as I was learning the system and parroted it to my players. We're all experienced with TTRPGs, for the record. Despite all the chat from pf2e players that you supposedly cannot ruin a character with bad choices, I assure you it is possible.
