Chant of Fortitude

 
Prerequisite(s): Concentration 8+ ranks, Perform (Any) 8+ ranks, Bardic Music
 
Benefit: You can expend one daily use of your bardic music as an immediate action to provide all allies (including yourself) the diehard feat until the end of your next turn. You can use this feat repeatedly to keep yourself and your allies conscious. If anyone goes down to –10 they still die.
