Final Fantasy VII Rebirth Aerith Solo Galian Beast Hard No Damage 

Aerith vs Galian Beast Solo Hard No Damage
Weapon level is 8 and party level 9
Goal was to skip phase 2 since I didn't feel like learning the perfect guard timings. Aerith even without maxed stats can do enough damage to oneshot the second phase. I used fira at points because if you do too much damage he'll enter phase 2 prior to stagger. If you stagger and get him to the damage limit he will always do Chaotic impulse leaving him stationary for Aerith to finish him off.
