Arcane Weapon — Anarchic

The magus can add the anarchic property to a weapon enhanced with his arcane pool, but this consumes 2 points of enhancement bonus granted to this weapon. An anarchic weapon is infused with the power of chaos. It makes the weapon chaotic-aligned and thus overcomes the corresponding damage reduction. It deals an extra 2d6 points of damage against all creatures of lawful alignment.
