Good amounts of Charisma, in the right hands, can also be used Against the players. Remember, Seduction(Charisma) can cause more problems than it solves! Like oh, you just seduced the mob boss’ wife, and she decides to keep seeing you, behind her husband’s back!
Or a player somehow successfully seduces a succubus early in a campaign, causing the BBEG of the campaign to just be an angry father.
Ah, good old charisma. It can open a lot of doors, and in my experience shut even more, seduce the big bad, somehow make a door blush and then open, and cause a guy to get hit every time he spoke (he had negative 3 charisma, so everyone had to roll not to hit him). I play weird DnD sessions and hear about even weirder one’s from my friends.
