At 19th level, when the swashbuckler confirms a critical hit with a light or one-handed piercing melee weapon, in addition to the normal damage, she can spend 1 panache point to inflict a deadly stab. The target must succeed at a Fortitude saving throw or die. The DC of this save is 10 + 1/2 the swashbuckler's level + the swashbuckler's Dexterity modifier. This is a death attack. Performing this deed does not restore panache to the swashbuckler.
