Preface: In any RPG the best character to play is one that fires up your imagination! A character that you’re having fun with will always be better, and play better, in-game than one that may be numerically better on paper, but doesn’t zing your thing.
“Character optimization happens at the table in Pathfinder 2e, not on the character sheet.”
– Logan Bonner, Pathfinder Lead Designer
So get a firm idea in your mind of a fun character that fires up your brain, then work with the rest of your group to bring them to the table as a team ready to experience epic stories!
