Unholy Weapon

Permanently enchant a melee weapon to often inflict a curse on the target, inflicting Shadow damage and reducing their melee damage.

This enchant can be made through Classic enchanting. It is taught by Formula: Enchant Weapon - Unholy.

A weapon enchantment that can curse its target. The curse deals some shadow damage and reduces the target's damage by 15. The curse lasts 12 seconds.

The visual effect added to the weapon consists of green skulls orbiting around it. Darkmaster Gandling seems to have enchanted his famous staff with Unholy Weapon but a more powerful curse occurs when fighting him.

In the patch 2.4.2 version the Unholy enchant does not show flying skulls on the Soul Harvester but it does process its Chance on Hit. The Unholy enchantment's visual effect also does not show up on any scythes, such as the Grim Scythe.
