You are especially hard to kill.
Prerequisite: Con 13 or Endurance.
Benefit: When your hit point total is below 0, but you are not dead, you automatically stabilize. You may choose to act as if you were disabled. You must make this decision as soon as you are reduced to negative hit points. If you do not choose to act as if you were disabled, you immediately fall unconscious.

When using this feat, you are staggered. You can take a move action without further injuring yourself, but if you perform any standard action you take 1 point of damage after completing the act. If your negative hit points are equal to or greater than your Constitution score, you immediately die.

(Base Fortitude Save +7): You are no longer staggered while under the effects of this feat.
