Armor Break is found on Auron's section of the Sphere Grid. It attacks and sets the target's Defense at 0, as well as nullifying "Armored", meaning that even non-Piercing weapons deal normal damage. The inherent armor property of armored enemies cuts physical damage to 1/3 if attack is not Piercing. Auron's Banishing Blade Overdrive alongside Frag Grenade (whether by Using or Mixing) are the two only attacks in the game that have 100% chance of inflict Armor Break, in contrast to Armor Break skill that not always inflicts this effect.
