Penetrating Strike

(Combat)
Your attacks are capable of penetrating the defenses of some creatures.
 

Prerequisites

Weapon Focus, 12th-level Fighter, proficiency with weapon.
 

Benefit

Your attacks made with weapons selected with Weapon Focus ignore up to 5 points of Damage Reduction. This feat does not apply to Damage Reduction without a type (such as DR 10/-).
 

Combat Trick

If you have a Stamina pool, the following Combat Trick may be used with this feat.
  Whenever you deal damage to a creature with Damage Reduction using the selected weapons, you can spend 5 Stamina points to allow all your allies (other than yourself ) within 30 feet of the creature to ignore 5 points of the creature’s Damage Reduction for 1 round. This has no effect on creatures with Damage Reduction without a type (such as DR 10/—). This effect does not stack with Penetrating Strike’s normal effect, but it does allow you to apply the effect to all your other weapons for the duration.
