Unholy [Property]

An unholy weapon is imbued with unholy power. This power makes the weapon evil-aligned and thus bypasses the corresponding damage reduction. It deals an extra 2d6 points of damage against all of good alignment.

An unholy weapon bestows one negative level on any good creature attempting to wield it. The negative level remains as long as the weapon is in hand and disappears when the weapon is no longer wielded. This negative level never results in actual level loss, but it cannot be overcome in any way (including restoration spells) while the weapon is wielded.

Bows, crossbows, and slings so crafted bestow the unholy power upon their ammunition.

Prerequisites: Craft Magic Arms and Armor, unholy blight, creator must be evil.

Unholy Surge [Property, Synergy]

This vile weapon is decorated with jagged spikes, skulls, and other macabre designs.

Characters who serve gods of murder, strife, and other base deeds craft these weapons of pure evil for themselves and for others who share their foul desires. This weapon functions as an unholy weapon. This is a continuous effect and requires no activation.

In addition, on a successful melee attack with an unholy surge weapon, you can command it to emit a burst of unholy energy, which deals an extra 3d6 points of damage to a good-aligned target. If used against a non-good creature, it deals no additional damage, and that use of the ability is wasted.

This ability is usable a number of times per day equal to 1 + your Cha bonus (if any). Once you activate this property, it can’t be activated by any other creature until the following day.

Prerequisites: Craft Magic Arms and Armor, unholy blight or unholy word.

Cost to Create: Varies.
