Irasceros Boss Fight Tips
Use Thunder Spells Thrice during Concentrate Use Lightning Ninjutsu to Deal Bonus Damage Against Irasceros Use Synergy Ability When Stagger Meter is 80% or More Use Braver When Irasceros is Casting Firaga to Prevent it

Cast Thunder Magic Thrice During Concentrate

The Irasceros will use Concentrate when their stagger meter reaches high. Equip the Lightning Materia, and when they use Concentrate, cast Thunder spells thrice to successfully interrupt the move.

How to Get the Lightning Materia

Use Lightning Ninjutsu to Deal Bonus Damage Against Irasceros

Irasceros is weak to Lightning attacks so use Yuffie's Lightning Ninjutsu to deal bonus damage against Irasceros. After casting Ice Ninjutsu, throw your shuriken using Triangle and spam basic attacks (Square) to deal ranged elemental damage.

Use Synergy Ability When Stagger Meter is 80% or More

Since Irasceros will use Concentrate when its Stagger Meter is high, immediately use any offensive Synergy Ability that you have in order to completely stagger Irasceros and prevent Concentrate from being used.

Use Braver When Irasceros is Casting Firaga to Prevent it

Irasceros can use Firaga which can deal massive damage to your character. However, this can be prevented easily with Cloud's Braver, as it will take some time before Irasceros can finish casting the Firaga.
