Your life-force is strong enough to make you highly resistant to all forms of energy drain and level loss.
Prerequisite: Must be a living creature.
Benefit: Whenever you are struck by an attack that drains energy or bestows negative levels, you gain an immediate saving throw to resist the effect at the standard Difficulty Class of the attack. If this initial save is successful, you avoid any negative levels but you still suffer any other effects of the attack or spell. If this save fails, the attack proceeds as if this roll had never been made (meaning you still receive whatever save to which you're normally entitled).
