Constitution

Constitution controls one's ability to bear pain, to deal with physical stimuli, to stay conscious, the physical fitness a person's body is in and many other applications of grit and durability.  A player officially loses a limb if the wound on any limb exceeds the maximum by an amount equal to their CON modifier. You may hold your breath for as many turns as your Constitution modifier. Each turn you are holding your breath, you temporarily lose 2 delay to your cap. When you reach zero, apply Suffocate.
