Spellsense [General, Save]
Your keen intuition allows you to recognize the emanations of magic directed against you.
Benefit: If you make a saving throw against a spell, you learn what the precise effect of the spell would have been and the location of the caster. If the caster is out of your line of sight, you have a sense of the general direction and distance from you, though you do not receive a name or any sort of visual image. If you fail your save, you may make a Will save (DC 15) to recognize the effect of the spell and the location of the caster at the time of the casting, but only after the effect has expired. In other words, if an enchanter casts charm person on a guard, once the effect is over she may realize exactly what has occurred — but that won’t help her while she’s under the influence of the charm.
Normal: A character who successfully saves against the effect of a spell knows that he was targeted with magic, but he does not know who the caster was or what the nature of the effect would have been.
