This skill represents your proficiency in, and knowledge of, the performing arts. It reflects training, screen presence, magnetism, and your ability to play to your audience.
Some performances require you to be more than just charismatic, and if you don't meet the demands of the art form or the audience, the GM might apply a penalty based on the relevant ability score. For example, if you're dancing and have a negative Dexterity modifier, you might take a penalty to your attempt at dancing. Likewise, if you are orating and have a negative Intelligence modifier, you might have to hope your raw Charisma can overcome the penalties from your intellectual shortcomings—or ask someone to help write your speeches!
The following are examples of Perform checks:
Act, Dance, Keyboards, Orate, Percussion, Sing, Stage Magic, Stand-Up, String Instruments, Wind Instruments
When making a brief performance—one song, a magic trick, or a quick comedy routine—you use the Perform action. This action is most useful when you want to prove your capability or impress someone quickly. Performing rarely has an impact on its own, but it might influence the DCs of subsequent Diplomacy checks against the observers—or even change their attitudes—if the GM sees fit.
Critical Success Your performance impresses the observers, and they’re likely to share stories of your ability.Success You prove yourself, and observers appreciate the quality of your performance.Failure Your performance falls flat.Critical Failure You demonstrate only incompetence.
