Defiant

This special ability can only be placed on melee weapons. A defiant weapon helps its wielder stay alive in desperate conditions. It stays in its wielder's hand even if she is panicked, stunned, or unconscious. She adds the weapon's enhancement bonus as a bonus on checks to stabilize when dying and on saving throws to end ongoing conditions such as disease, poison, and hold person. If the wielder possesses Heroic Defiance, Heroic Recovery, Improved Great Fortitude, Improved Iron Will, or Improved Lightning Reflexes, she gains a number of additional daily uses equal to the weapon's enhancement bonus that can be used on any of these feats.
