Dark Resilience (Su)

The black blood flowing through a black-blooded oracle’s veins gives her resistance to many effects to which undead are immune. Once per day, as an immediate action, whenever she fails a saving throw against an ability drain, a death effect, disease, energy drain, paralysis, or poison, she may attempt that saving throw again with a +4 circumstance bonus. She must take the second result, even if it is worse. At 7th level, she can use this ability twice per day. At 15th level, she can use the ability 3 times per day.
