Arterial Strike

 
Prerequisite(s): Sneak Attack, Base Attack Bonus 6+
 
Benefit: If you succeed with a sneak attack, you can choose to forego 1d6 of the damage and cause a wound that will not stop bleeding. Each wound delivered in this fashion, causes an additional 1Hp loss per round until the target receives magical healing or a successful DC15 heal check.
