Profane [Property]

This black iron weapon is decorated with a single silver skull. A runic phrase describing a vile act runs along its blade or haft.

By speaking the appropriate command word, you can sheathe a profane weapon in crackling black negative energy. If you have no Constitution score, this energy does not harm you; otherwise you take 1 point of Constitution damage for each round that you hold the weapon while the effect is activated. This effect lasts until you speak another command word to end it.

While activated, a profane weapon deals an extra 1d6 points of damage to any living target (or 2d6 points against a good outsider) on a successful hit. Also, it is treated as evil-aligned for the purpose of overcoming damage reduction.

Projectile weapons bestow this property upon their ammunition.

Prerequisites: Craft Magic Arms and Armor, inflict light wounds.

Cost to Create: Varies.

Profane Burst [Property, Synergy]

This black iron weapon is decorated with dozens of silver skulls. Runic phrases describing vile acts run along its blade or haft and glow when it is wielded.

A profane burst weapon functions as a profane weapon. In addition, the weapon explodes with negative energy on a successful critical hit, dealing extra negative energy damage as set out in the table below. (This effect activates even if the target is not normally subject to extra damage from critical hits.)

A profane burst weapon deals even more damage to good outsiders on a successful critical hit. This burst does not harm you or any creature other than the target if you are undead; otherwise, you take 1d4 points of Constitution damage (or Charisma damage if you have no Constitution score). This is a continuous effect and requires no activation. Even if the weapon has not been activated to deal extra damage because of the profane property, the weapon still deals its extra negative energy damage on a successful critical hit.

Projectile weapons bestow this property upon their ammunition.

Prerequisites: Craft Magic Arms and Armor, inflict critical wounds.
