Anarchic

An anarchic weapon is infused with the power of chaos. It makes the weapon chaotically aligned and thus bypasses the corresponding damage reduction. It deals an extra 2d6 points of damage against all creatures of lawful alignment. It bestows one permanent negative level (Core Rulebook 562) on any lawful 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 cannot be overcome in any way (including restoration spells) while the weapon is wielded.
