Axiomatic Strike
(Player's Guide to Faerûn, page 135, DnD 3.5)
[Epic]
Your attacks deal incredible damage to chaotic creatures.
Prerequisite
Smite anarchy class feature, any lawful alignment
Benefit
Any weapon you wield is treated as an axiomatic weapon (lawful-aligned, deals an extra 2d6 points of damage against creatures of chaotic alignment). If the weapon already has an alignment, this feat has no effect on it.
