You have an amazing knack for avoiding terrible situations.
Benefit: Instead of being able to reroll a single Fortitude save, a single Reflex save, and a single Will save each day, you may instead reroll a total of five saving throws in whatever combination you choose. For example, you could reroll two Reflex saves, two Will saves, and one Fortitude save, or five Fortitude saves. You need not choose the combination in advance. This otherwise functions as the Improved Great Fortitude, Improved Iron Will, and Improved Lightning Reflexes feats.
