Song Of Defiance

This is a Song:Undying Word — a class feature gained through that class's own talent choices, not a feat you pick through normal feat selection.

At 6th level, an undying word can shield his allies against the environment. By expending 1 round of raging song, the undying word grants all allies within 60 feet the effects of endure elements for the next hour. The undying word must continue to perform for the remainder of the hour; otherwise its effects end, but only 1 round of raging song is expended for that hour.

This raging song replaces song of strength.
