After failing a saving throw against a magical effect with a duration longer than 1 round, you can attempt a second saving throw the following round to shake off the effect. If you succeed on this second saving throw, you gain a +2 insight bonus to saves against magical effects produced by the creature whose effect you just saved against; this bonus lasts for 24 hours.
