P148 states: So damaging a 2 point arm for 5 points brings the arm to -2 HP and subtracts 4HP from the adventurer's total HP. It is implied that if the arm is hit again, more damage can be inflicted on the adventurer's total HP.  What is the limit?  If the arm is damaged for another 3 points in a subsequent attack does it now go to -5 HP and is another 3 points subtracted from the total HP?     It does not stae that the head, chest or abdomen are limited to twice as much da
