An Artist is trained to use the Perform Skill to cast fantastic effects on those around them, including them self. They can use this ability for a number of rounds equal to either EGO Mod or ID Mod. With every stack, The Artist may use the ability for an additional round +1.
Starting a Performance is a Main Action, but it can be maintained each round as a Bonus / Main Action. Changing Performance requires The Artist to stop the current, and start a new one as a Main Action. A Performance ends immediately if The Artist is killed, paralyzed, stunned, knocked unconscious, or otherwise prevented from doing a Bonus or Main Action to maintain it. Artists cannot have more than one Performance in effect at a time.
If an Artist is missing the body parts needed for a Performance, or is otherwise restricted somehow, they cannot Perform.
If a Performance has Audible / Verbal Components, the targets must hear for the Performance to have an effect. A deaf Artist must make a Coin Flip when attempting to use such a Performance. Failed attempts still count against their daily limit.
If a Performance has Visual components, the targets must see for the Performance to have an effect. A blind Artist must make a Coin Flip when attempting to use such a Performance. Failed attempts still count against their daily limit.
