Charisma is both Charm and Frighten. Highly charismatic people do both.You don't need to be the face guy (=put points in Charisma) to "persuade" people to cooperate. You don't need to be eloquent or witty in order to threaten people with extreme amounts of pain unless they do what they're told.
Some ways of being charming can be to be eloquent. But the "silent type" can also be charismatic. Compare Clint Eastwood.
I see eloquence and wit as Intelligence. Albeit, to express Intelligence in an artistic esthetic way that a crowd would enjoy applies Charisma Performance.
I use Performance for various efforts to check for artistic appeal. For example, painting a photorealistic painting involves Dexterity Sleight for technical precision, Perception to depict perspective, lighting, and so on accurately, and Charisma Performance for the overall artistic appeal to please crowds. High scores in all checks, especially Performance, can represent a potentially valuable painting. Artists generally need to gain fame thus higher tiers before they can monetize artwork in this way, tho a wealthy person might patron an artist early on.
