Inflicting the Horrendous Wound
From DivNull RPG
A sudden outpouring of savage brutality can leave an opponent stunned and disoriented, tending to nothing but the pain his new scars are bringing him. This charm supplements a martial arts attack. For each HL of damage he successfully inflicts on an opponent with this attack, that opponent will be at -1 on all his die pools for the rest of the scene. This cannot reduce the opponent's die pool below his permanent Essence.
