Even when the chips are down, you keep on shooting.
Benefits: If your hit point total drops to 0 or lower but you are not dead, you may act as if disabled rather than dying (as if you possessed the Diehard feat). However, you can use your actions only to draw a firearm, reload a firearm, or attack with a firearm. If you have the Diehard feat, this trait also allows you to substitute your Wisdom score for your Constitution score for the purpose of determining the negative hit point total at which you die.
