Yeah, he was a condescending sexist prick to the Kiyoshi warriors (initially), and while it did earn him some beatings, it didn't get him a restraining order and he even got with Suki in the end. That's high CHA alright.
I don't know about you, but to me, the fact that he showed genuine humility and willingness to step beyond his initial chauvinism (after some hands-on lessons about fighting women) had a lot more to do with that than his charm.
In Pathfinder 1e, it mentions that high charisma can mean an attractive person. We know this can be true because my bard had a 36 cha (PF1e is broken lmao) and we all know it wasn't his personality.
Yeah, but it affects ALL charisma rolls, so it's effectively just a permanent CHA boost applied directly to the character. No functional difference from naturally high CHA, IMO.
Wait.
It doesn't work if target doesn't have LOS, so loophole found, we just have to invent the internet or telephone in-universe to nullify sokka's advantage.
Edit: or drop a permanent orb of darkness over him so nobody can see what he looks like
I get that this is a bit, but even in D&D charisma and attractiveness are different. Unless the elder brain is supposed to be sexy, then I need to rethink some things.
