Magic Weapon Abilities - Sacred Burst

A sacred burst weapon functions as a sacred weapon that also explodes with positive energy upon striking a successful critical hit. (This effect occurs even if the target is normally immune to critical hits.) The positive energy burst does not harm the wielder unless it is undead, in which case it takes 1d4 points of Charisma damage each time the weapon bursts. In addition to the extra damage from the sacred ability (see above), a sacred burst weapon deals an extra 1d10 points of damage to undead on a successful critical hit. If the weapon's critical multiplier is x3, add an extra 2d10 points of damage instead, and if the multiplier is x4, add an extra 3d10 points. (Double the bonus dice of damage against evil outsiders.) Bows, crossbows, and slings so crafted bestow the positive energy upon their ammunition. Even if the sacred ability is not active, the weapon still deals its extra damage on a successful critical hit.
