Monado Purge (XC1)

Monado Purge (, Monado Breaker), often shortened to just Purge (, Breaker), is one of 's Monado Arts in Xenoblade Chronicles and Future Connected. It involves Shulk firing a green crescent of energy at the target, which clears its active s and inflicts Aura Seal so it cannot quickly create another. It also neutralizes abilities for the duration and deals ether damage.

Overview
Monado Purge doesn't really have much use in battles where enemies do not have auras or spikes, as Shulk is typically better at dealing physical than  damage and Purge isn't a powerful art in terms of damage to begin with. However, when up against a foe with a powerful aura or a deadly spike, Shulk should usually save his talent gauge to keep using Purge and ensure the party is safe from the aura or spike's effects. This is especially true against Telethia, where if Shulk cannot build his talent gauge in time he has no choice but to use Battle Soul (to make up for not being able to hit the Telethia with s) or flee the battle entirely.

Monado Purge is the only ether attack Shulk can have during the minor portion of the story where he can fight people with the Monado. While the Monado normally cannot hurt people, it can with ether attacks if the target is d. As a result, if Shulk gets stuck in such a battle, Purge is his only means of damaging them.
