Quetzalcoatl Tips and Strategies

Biological Intel: Blinded by Light Tips
Use Aerith to cast Blizzard twice
Use Cloud and TIfa to quickly stagger it
Use Aerial and Magic Attacks When Enemies Fly
Move Away during Electrodiffusion

Use Aerith to Cast Blizzard Twice

Exploiting Quetzalcoatl's weakness, Ice, will pressure it. Use Aerith to do this. To make it more effective, have her use Arcane Ward first, which can be unlocked permanently after mastering it from Guard Stick. You can cast Blizzard twice within this ward, so make sure to prioritize this move!

Use Cloud and Tifa to Quickly Stagger Quetzalcoatl

Once Quetzalcoatl is Pressured, have Cloud or Tifa use their abilities to quickly fill the Stagger Bar. Moves like Cloud's Focused Thrust and Tifa's Focused Strike will do the trick here. Once it's staggered, unleash all available damaging abilities until Quetzalcoatl is taken down.

Use Aerial and Magic Attacks When Enemies Fly

When Quetzalcoatl starts flying, have Aerith cast Radiant Ward to increase her basic attack effectiveness. You can also have Cloud or Tifa perform aerial attacks to deal damage while this creature is in the air.

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

When Quetzalcoatl uses Electrodiffusion, which deals strong AOE lightning damage around itself, make sure to keep your distance to avoid this attack as this will deal huge damage to the party.
