As long as you have an audience, you can continue to perform even when you are on the brink of collapse. Indeed, you must-- you have an obligation to your fans! You delay the effects of the fatigued condition for 1 minute or until you are no longer observed by at least three creatures who aren't enemies, whichever comes first. If the fatigued condition has a duration, the duration begins to elapse only after the delay. You can't further delay or prevent the fatigued condition after this ability ends.
