Unholy Strike

(Epic Level Handbook, page 68, DnD 3.0)

[Epic]

Your attacks deal great damage to good creatures.

Prerequisite

Smite good class feature, any evil alignment

Benefit

Any weapon you wield is treated as a unholy weapon (it deals +2d6 points of damage against creatures of good alignment). This ability doesn't stack with similar abilities (for instance, if the weapon is already an unholy weapon).
