How to Beat Biological Intel: Breath of Life

Biological Intel: Breath of Life Tips
Presure the Enemies by Exploiting Weaknesses
Stagger the Archdragons Carefully
Use Aerial and Magic Attacks When Enemies Fly
Move Away during Electrodiffusion

Pressure the Enemies by Exploiting Weaknesses

The Quetzalcoatl is weak to Ice attacks, while the Archdragons are weak to Wind attacks. Exploit these weaknesses with spells to pressure the enemies. Once they are pressured, you can use Cloud's Focused Thrust if they are on the ground to quickly stagger them.

Stagger the Archdragon Carefully

The Archdragons have low health, so you need to be careful not to accidentally kill them without staggering. You can switch to Tifa and charge her ATB gauge by locking onto Quetzalcoatl first. Then, you can use Aero on the Archdragons to pressure them, and follow it up with basic attacks to stagger.

Use Aerial and Magic Attacks When Enemies Fly

When the Quetzalcoatl starts flying, you can switch to Aerith to cast Ice spells or ranged basic attacks on it. You can also get Cloud and Tifa to perform aerial attacks when their ATB gauge is empty. Although, note that these characters can only use certain abilities while in the air.

How to Perform an Aerial Attack

Character	How to Aerial Attack
Cloud	・ Press then Hold after to launch into the air. ・ Use the Triple Slash or Firebolt Blade abilities to launch into the air.
Tifa	・ Unlock Leaping Strikes in Tifa's Folio ・ Use the Soaring Flurry or Heavenly Ascent Synergy Skills to launch Tifa into the air.

How to Attack Flying Enemies

Move Away during Electrodiffusion

At some point, Quetzalcoatl will use Electrodiffusion, dealing strong AOE lightning damage around itself. When it starts raining lightning attacks, make sure to move away and keep your distance to avoid this attack.
