If I understand you correctly, the Charisma stat might be better named "Natural Leadership Ability", except that that's too long a name for a stat.

And, thinking of how it works for conjurers and bards, I guess that kinda makes sense.

But maybe it would be a good idea to change the words which show up in score to describe it? I know I've felt bad playing a persuasive character with low charisma -- so much so that I've had times where I've changed my role play to be more in line with the stat description.

I don't have any good ideas for what the names should be, but maybe this could be a "Valguarnera's Monthly Contest" at some point?
