(General)
Your thorough understanding of acoustics in artificial surroundings allows you to improve the power of your bardic performance.
Prerequisites
Bardic performance class feature,
Knowledge (engineering) 5 ranks.
Benefit
While inside an artif icial structure, you can spend a
Free Action to make a DC 15
Knowledge (engineering) check when you begin your bardic performance. Success on this check allows you to do one of the following. Self-Harmonize: By performing over the acoustic reverberations of your performance, you increase the DC of your bardic performance effects +1. Reverberation: You can choose to have the effect of your current bardic performance continue for 1 round after you cease maintaining it, regardless of why you cease maintaining it. You can still have no more than one bardic performance in effect at one time.
Normal
A bardic performance lasts only as long as you maintain it.
