Chaotic Rage
(Epic Level Handbook, page 51, DnD 3.0)
[Epic]
Your rage is particularly damaging to lawful creatures.
Prerequisite
Rage 5/day, chaotic alignment
Benefit
Any weapon you wield while in a rage is treated as a chaotic weapon (it deals +2d6 points of damage against creatures of lawful alignment). This ability does not stack with similar abilities (for instance, if the weapon is already a chaotic weapon).
