Defend is a support ability that the Squire job learns it for 50 JP. Equipping Defend in the support ability slot will add a Defend command in the unit menu. This ability doubles the character's chance of evading an attack until his next turn and starts the character CT from 20 rather than 0, meaning earlier action in the next turn. Thief's reaction ability, Vigilance, can trigger the defending stance when the user is being attacked.
