Key Attribute: Charisma.
The Performance skill encompasses a character's talents in entertaining and captivating an audience through various artistic mediums. It governs abilities such as singing, dancing, acting, playing musical instruments, oratory, storytelling, and any other form of stagecraft or public performance.
You must select a specific form of Performance—a musical instrument, singing, poetry, oratory, painting or what have you—but working outside your specialty merely imposes slight on your skill checks, rather than restricting you outright. When you choose to upgrade Performance, you may elect to add a new specific form instead of taking another skill rank.
You can use Performance to Calm a Foe, Impersonate Another or Make an Impression.
