===Hit Points===
Your hit points are your ability to withstand blows without being seriously injured. Your hit points total is your (Health ranks + 2) * Racial health value. Every time you received damage, you subtract them from your current hit points. When your hit points total reaches 0, you lose Constitution points instead when injured. While at 0 hit points or below, you are disabled.

While disabled, you might lose consciousness because of the extreme pain you suffer. Each time you take an action or at every Long action (whichever is lower), you need to make a Constitution check DC 10 + your negative hit points score to stay conscious. If you failed your check, your unconscious. If you succeed, you manage to stay conscious. On a total success, you stabilize and do not need to do further check to stay conscious until you're hurt again, but you are still disabled.

''Temporary Hit Points:'' When you gain temporary hit points, note your current hit point total. When the temporary hit points go away your hit points drop to your current hit point total. If your hit points are below your current hit point total at that time, all the temporary hit points have already been lost and your hit point total does not drop further. When temporary hit points are lost, they cannot be restored as real hit points can be, even by magic.

''Increases in Constitution or Health and Current Hit Points:'' An increase in your Constitution or Health skills, even a temporary one, can give you hit points (an effective hit point increase), but these are not temporary hit points. They can be restored and they are not lost first as temporary hit points are.
