You can make an attack to weaken your opponent. Make an unarmed attack with a MartialArts check. If successful, the opponent suffers (in addition to normal damage) 1 point of impairment for every full 5 WoundPoints suffered.
Wound Points delivered from a Hamstring attack can be healed normally (unlike the Rat schtick Infect).
If you pick this schtick twice, you can use it with a melee weapon. If you pick it thrice, you can use it with a gun.
