Storm Cannon (シュトルムカノーネ, Shutorumu Kanōne?) is a Blue Bullet spell in Final Fantasy X-2. Learned from the Ironside enemy, it deals non-elemental magic damage to all enemies equal to 30 times the caster's level for the MP cost of 38.
In the HD Remaster and International versions, capturing and releasing a Stalwart to see its Fiend Tale will allow the fiend to be encountered in Standard Cup Hard or Grand Cup Hard tournaments. This Stalwart can also use Storm Cannon, allowing players an alternate way to learn the ability.
