Aura Bullet

Aura Bullet is one of 's support s in Xenoblade Chronicles. It extends the duration of the target's current aura.

Overview
Most auras are quite beneficial to extend, especially if they can reach the point where they last longer than their cooldown (or just about), which is possible for some when highly-levelled. There's not much strategy involved, aside from having decided beforehand which aura the plan is to extend, and making sure that the art isn't used when no aura is active.
