Battle Eye

Battle Eye is one of 's aura Battle Arts in Xenoblade Chronicles. It attempts to apply Lock-On to the target, and if it succeeds, Dunban gains a 25% double attack rate and gets 5% talent gauge per successful dodge for the aura's duration.

Overview
Battle Eye has two effects. Combined, the aura allows Dunban to do his job as a tank even if he's being ineffective at building aggro normally. However, its long cooldown means he cannot rely on it.
 * It inflicts lock-on. This is most useful if Dunban is having trouble getting aggro the old-fashioned way via damage.
 * It raises double attack rate, as well as granting talent gauge for every attack dodged. Double attacks are usually not a reliable means of damage, but it does give Dunban a damage boost that no other effect overlaps. The extra talent gauge when dodging is essentially a way for Dunban to build Blossom Dance if he has trouble hitting the enemy (which matches with the first point, where he isn't dealing enough damage to get aggro).
