Glorious Epic (Su)
Source: Advanced Player's Guide, p. 81
A court bard of 8th level or higher can weave captivating tales that engross those who hear them. Enemies within 30 feet become flat-footed unless they succeed at a Will save (DC 10 + 1/2 the bard’s level + the bard’s Cha modifier). A save renders them immune to this ability for 24 hours. Glorious epic is a language-dependent, mind-affecting ability that uses audible components. This performance replaces dirge of doom.
