Type: Divine
Source: Fiendish Codex II
You can channel divine energy to make a second save against an effect that specifically targets you.
Prerequisite: Ability to turn or rebuke undead.
Benefit: As a swift action, spend one of your turn or rebuke undead attempts to make another save against any effect that targets you and has a continuing duration. For example, on his turn, a cleric with this feat who fails a saving throw to resist the effect of a hold monster spell can spend a turn undead attempt as a swift action to attempt another save.
