Your attack leaves your opponent gasping for air and watching spots dance before his eyes.
Prerequisite: Base attack bonus +4, sneak attack +3d6.
Benefit: By reducing your sneak attack damage by two damage dice you can make a special melee attack targeting your foe's vital organs that forces your target to make a Fortitude save (DC 10+1/2 your class level + your Int modifier). If your target fails this save, at any time in the next 10 minutes that he attempts to make a Strength-, Dexterity-, or Constitution-based skill check or on ability checks using one of these scores he becomes fatigued. If already fatigued he becomes exhausted instead.
