You can be low Cha and skilled at things like bluffing or intimidating- just take ranks in those skills.
I said naturally good at feint. Ranks in skills denote learned experience. Bonus from stat denotes natural ability.
I'm saying that I think a person can be not be a good leader (low CHR) but be good at the melee feint, and not having trained in either. Not naturally gifted with a powerful personality but naturally gifted at performing the feint.
Neither circumstance speaks to skill ranks.
Explain to me why they later introduced "trait" mechanic doesn't handle the scar in a way that comports with your sense of how it should work?
Trait mechanic? You mean the circumstance bonus?
