Sacred Resilience

 
Prerequisite(s): Ability to turn undead, Unquenchable Flame of Life or Unyielding Bond of Soul
 
Benefit: If an ally within 60' would be required to make a save against hit point damage from an Extraordinary or Supernatural ability from a creature type for which you have the appropriate prerequisite feat (undead or evil outsider), you can spend a turn attempt as an immediate action. This grants your ally the same bonus on the save as the feat would grant you. You must decide to invoke Sared Resilience before yor ally rolls the saving throw. If you have both Unquenchable Flame of Life and Unyielding Bond of Soul, you can apply Sacred resilience to resist attacks from both creature types. You need not take the feat a second time.
