Attack Order (AO) is a stat in the Luminous Arc Series. It makes it's first appearance in Luminous Arc 2: Will. The AO stat determines the ability of a character to act within the battle. Units with higher AO act more often, giving them more actions in battle. If there are two or more units with the same amount of AO, the one with the highest Speed stat always acts first.
