Bardic Performance (Ex) A sige has the bardic performance abilities of an 18th-level bard, granting it access to that ability's countersong, distraction, fascinate, inspire courage, inspire competence, suggestion, dirge of doom, inspire greatness, soothing performance, frightening tune, inspire heroics, and mass suggestion performances.
Song and Silence (Su) A sige's bardic performance and spell-like abilities ignore the effects of any silence spell or spell-like ability. They can be heard normally within the radius of any such silence effect, and affect creatures within that radius as if no silence spell or spell-like ability were in effect.
