Grifter

You are a master grifter. 

Your charisma is 20. 

You gain expertise in deception, persuasion, and insight. 

You have become a master of social manipulation. In any conversation that lasts for more than a minute you may, through body language and conversation, either soothe or heighten any emotion in the creature you are talking to. By doing this you can either give yourself advantage on the next social check you make with them, or give them disadvantage on the next social check they make. This affect lasts for 1 hour.
