Expand: Piercing Aura charges all party members' next attack, boosting their power and enhances them with the Pierce effect. It is essentially a party-wide Impaler's Animus. The effect cannot stack with other charging effects, such as Charge, and will overwrite them if used afterwards.
- Although "Expand: Piercing Aura" is a descendant of Impaler's Animus, in the English translation, the name of the original skill isn't consistent ("Expand: Impaler's Animus.") This trait isn't present in the Japanese version, where the same skill is referred to the same way.
