You can sense magic energies and identify spells you save against.

Benefit: You can sense the presence of enchanted items or spell effects within 30 ft., identifying which items or areas are magical. In addition, whenever you succeed at a saving throw against a spell, spell-like ability, or supernatural ability, you know what would have happened had you failed your save. This is considered an extraordinary ability.

Special: This ability to sense enchanted items or spell effects does not allow you to bypass or reduce the effects of blindness or concealment in combat.

Normal: A creature that successfully saves against a spell without an obvious physical effects feels a hostile force or tingle but cannot deduce the exact nature of the attack.
