The character gets stronger when hurt or injured. When down to half his normal SDC total, he gains a bonus of +4 to PS and +10 to Spd. at this point the character cannot become fatigued. When down to zero SDC he gains an AR of 12 and a further +4 to PS and +10 to Spd. When on half HP or less his natural AR shoots to 14 and he gains a further +4 to PS. When down to his last 10 HP, he gains a sudden burst of 30 bonus SDC and begins healing 1D4 HP per melee round until he reaches 10 or higher HP.
The character can continue working and acting up to negative his PE score. During this time he has half his attacks and combat bonuses. He does not die until reaching a point below zero equal to double his PE score.
