DEFIANT LUCK [Human]

     You can sometimes shrug off spells and lethal damage that would kill a lesser creature.

Benefit: Once per day, after you roll a natural 1 on a saving throw or a critical hit is confirmed against you, you can either re-roll that saving throw, or force the creature that confirmed the critical hit against you to re-roll the critical confirmation roll.  This does not stack with other effects that allow you to re-roll a saving throw or an attack roll. You may only make one re-roll.

Special: You may spend 1 Hero point to force a creature to re-roll a confirmed critical hit against you.  This is in addition the free re-roll that is granted by this feat and can be used as many times as you have Hero points.  You cannot re-roll a saving throw in this manner.
