The Armor Penetration Armor Kit is an armor reinforcement kit that can be crafted in the Tailoring Profession.
Armor kits can be double-clicked to become active. Once the kit is active, a piece of armor can be selected, which applies the Reinforcement. Each armor piece can only be affected by one armor kit. Once applied, a Reinforcement cannot be removed, only replaced. Using the Armor Kit consumes it.
