From D&D Wiki
Prerequisites: 13 Charisma or higher, proficiency in Persuasion.
You’ve honed your wiles to a point. Your Proficiency Bonus is doubled for any ability check you make that uses Persuasion. In addition, when you make a Persuasion check against a creature you can see within 10 feet of you, they are considered charmed by you for 1 minute. If the creature is damaged or targeted by a spell while charmed, they are no longer charmed and the creature is immune to being charmed by you for 1 hour.
