Description
The tip of this heavy javelin is designed to break off and embed itself into a shield once it hits. Like ammunition, a thrown pilum that hits its target is destroyed. If you hit a shield-using opponent with a pilum, he loses the AC bonuses from that shield until he takes a standard action to pry the remnants of the pilum from his shield.
