Cactuar Crush Stage 3 - Yuffie - Hard Mode (Final Fantasy VII Rebirth)

This was very painful and took forever. Doppelgänger is a must. If you don't have it, learn it, and come back. I recommend the Speed Demon Keychain as your accessory, as well as materia like Speed Up, Strength Up, Magic Up, Luck Up, and ATB Stagger. You want to have your ninjutsu out most of the time, even against cactuar with magical defense, because your main goal is to rack up ATB. Windstorm is your best friend. If you have ATB, spam Windstorm. Re-summon your doppelgänger as soon as it disappears. For the big cactuars, use Banishment, and if your doppelgänger is alive you will inflict massive damage on them. Also, be on the lookout for cactuar attacks, which will start coming more frequently towards the end. Don't just play pure offense, because you lose points each time you get hit, and you can't afford to take that many hits if you want to reach 6000 points. The first time I completed this challenge, I ended up with 5900 because I took too much damage, which felt very bad.
