Almost all of Auron's massive blades bear the Piercing ability, so you should bring Auron into battle when facing an enemy with a hard shell. Auron is ineffective at attacking nimble or aerial creatures, but his Break abilities reduce the attacking and defending power of most enemies.

As Auron gains Sphere Levels, his HP and Strength will skyrocket. Once he reaches the end of his section, it's a good idea to transport him into Tidus' section. By doing so, you can increase his Agility so he can attack more often.

Auron's Overdrives require the swift input of button combinations before the time limit runs out. The quicker you can input the sequence, the more powerful Auron's attack becomes. Auron gains new Overdrives through the acquisition of recorded spheres that recount the journey of Auron's adventures with Braska. After defeating the Spherimorph at Lake Macalania, you can locate Jecht's and Braska's Spheres that are scattered across Spira.

The status ailments are inflicted only when the command input is successful, although certain enemies can resist the ailments. If resisted, the damage inflicted is slightly increased to compensate.
