Holy, Lesser (3.5e Equipment)
From D&D Wiki
Lesser Holy: A low powered version of the Holy enchantment, it too is imbued with holy power. This power makes the weapon good-aligned and thus bypasses the corresponding damage reduction. It deals an extra 1d4 points of damage against all of evil alignment. It bestows one negative level on any evil 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 holy power upon their ammunition.
When combined with the Holy Enchantment the damage rises to 1d6 (for a total of 3d6), but the negative levels do not stack.
