Under normal conditions, this shield acts as a normal heavy spiked shield. However, if the wielder has the Exotic Weapon Proficiency (Vanguard Shield) feat, it becomes much more interesting.
The wielder is now able to use the shield to defend against combat maneuvers such as disarming, sundering, or tripping attempts, granting its shield bonus (and any associated enhancement bonus) to the defensive check. Additionally, the vanguard shield provides a +2 circumstance bonus on any bull rush and overrun attacks made with the shield.
Beyond that, the sharpened edges of the shield can be used to make attacks much like a spiked shield, including being able to be enchanted separately as a weapon, though dealing slashing rather than piercing damage.
