When an investigator has 1 or 2 hit points left, he or she automatically falls unconscious, and no longer actively participates in the game. Thought living, he or she will not wake until hit points rise to 3 or more.  The keeper may privately determine an alternative length of unconsciousness.
Time may heal the wound enough that the investigator can stagger away, or her or she may be helped by successful First Aid orMedicine Roll.
