Build up the ATB Gauge and use as many abilities as you can when fighting the Mindflayer. The main goal here is to access Synergy Abilities as soon as possible to pressure this boss.

Once pressure, use Cloud's Focused Thrust to quickly fill the Stagger bar.

With the same idea as with Cloud, use Tifa's abilities as much as you can to access synergy abilities. Once Mindflayer is staggered, use her Unbridled Strength into Omnistrike combo to deal tons of damage.

Mindflayer Tips and Strategies

Biological Intel: At Any Cost Tips
Use Synergy Abilities to Pressure it
Use Cloud's Focused Thrust to Stagger it
Use Counterfire against its magic attacks
Hide behind boulders during Psychotic Break

Use Synergy Abilities to Pressure Mindflayer

The only way to Pressure Mindflayer is to use Synergy Abilites on it. To access these abilities, use as many weapon abilities as you can. We recommend using Cloud and Tifa's Relentless Rush to increase your attack power.

All Synergy Abilities and How to Use

Use Cloud’s Focused Thrust to Stagger Mindflayer

Once pressured, use Cloud's Focused Thrust ability to quickly fill Mindflayer's Stagger bar. It's important to get it into this state as soon as possible to deal tons of damage, since it has no elemental weakness we can exploit.

Use Counterfire Against Mindflayer's Magic Attacks

It's recommended to have the Synergy Skill, Counterfire, equipped in your Folio. This is an ideal move to counter Mindflayer's magic attacks. Using this will also fill the ATB gauge, which will allow you to use more abilities and, in turn, more Synergy Abilities.

All Synergy Skills and How to Use

Hide Behind Boulders During Psychotic Break

Mindflayer's move, Psychotic Break, will deal lots of damage if you're not careful. To prevent this, hide behind one of the boulders that will appear and wait until the move is over before coming out. Don't worry; the AI for your other party members will do the same so don't worry about them getting knocked down.
