You amplify your voice, loud enough for you to be heard easily at a great distance. For the duration, your voice can be heard loudly and clearly by all listeners within 500 feet, even if other ambient noise would otherwise block the sound. Despite the volume, this doesn't make your voice jarring or distracting. This doesn't increase the range or area of other
auditory or
linguistic effects, and physical barriers such as walls and doors still block or muffle your voice as normal.
Your loud voice makes it easier to
Coerce others, and the acoustics assist in
Performing at a large venue. You gain a +1 status bonus to checks to Coerce and auditory
Performance checks to Perform at a large venue.
