You can overcome magic effects through pure force of will.
Benefit: Once per round, when targeted by a spell or effect that allows a Reflex save or a Fortitude save, you can instead make a Will saving throw. You may use the ability a number of times per daya equal to 3 + your Wisdom bonus.
Special: If you have this feat and gain a caster level, you may immediately decide to permanently forgo any spellcasting ability and retain this feat. If you do not make this decision this feat is lost, and cannot be replaced.
