Arcane Weapon — Brilliant Energy

The magus can add the brilliant energy property to a weapon enhanced with his arcane pool, but this consumes 4 points of enhancement bonus granted to this weapon. A brilliant energy weapon ignores nonliving matter. Armor and shield bonuses to AC (including any enhancement bonuses to that armor) do not count against it because the weapon passes through armor. (Dexterity, deflection, dodge, natural armor, and other such bonuses still apply.) A brilliant energy weapon cannot harm undead, constructs, or objects.
