Use Gunner skills.
In-Game "Help" Description.
Gunplay (ガンプレイ, Ganpurei?) is the Gunner-exclusive skillset in Final Fantasy X-2. Most Gunplay abilities have various support abilities, which at times may give the player the upper-hand. Gunplay abilities have no charge time and execute on-the-go, but have rather high MP cost in comparison to Gunner's MP growth if the player aims to utilize the dressphere to its full power.

Gunplay is a general term for the discharge or exchange of gunfire. Gun fu, a portmanteau of gun and kung fu, is the style of sophisticated close-quarters gunplay seen in Hong Kong action cinema and in Western films influenced by it. It often resembles a martial arts battle played out with firearms instead of traditional weapons. It may also be described by other terms such as bullet ballet, Gun Kata, or gymnastic gunplay.
