Final Struggle, A Second Wind

Just because you are near death, does not mean that death is the only way.

If your health becomes zero, you can use pure adrenaline to push through and gain a second wind.  At a permanent cost (barring any divine intervention) of -1 Constitution, you can revive with 10 HP.  If you are defeated after using this feat during the same combat, you forfeit all saving throws and immediately die.  You cannot be revived by normal means and can only have their life returned to them through divine intervention.

We just did an awesome job of not dying. - Tom Green
