Thunder Bullet

Thunder Bullet is one of 's ether s in Xenoblade Chronicles. It does two hits of damage and has a +25% critical hit rate against flying enemies.

Overview
Thunder Bullet is Sharla's fastest art to recharge and is decently powerful, so it is likely to be used often. The extra crit rate on flying enemies is more of a bonus than a practicality, especially since the definition of "flying" is left unclear (e.g. whether nebulae or hovering Mechon count).
