Penetrating Shot (Ex)
Replaces: Armor Mastery
At 19th level, when a crossbowman confirms a critical hit with a crossbow, the bolt pierces the target and can strike another creature in line behind it. The crossbowman must be able to trace a line starting at his space and passing through both targets to make this additional attack. The secondary attack is made at a –4 penalty, in addition to any modifiers for added range. If this attack is Classes 2 also a critical hit, the bolt can continue to hit another target, but the penalties stack. This ability replaces armor mastery.
