Final Fantasy 7 Remake Hard Mode: 10 ESSENTIAL Secrets, Tips & Tricks

7. Only Use Level 3 Attack Spells On Staggered Bosses

Simply because you're only going to be recovering mana in between chapters (making chapter 17 one HELL of a slog), you really shouldn't be using spells whatsoever, until a boss is staggered.

Brilliantly though, if something is weak to a particular element, even a level 1 cast will increase their stagger gauge considerably, often knocking them out of an attack too.

I'll get into a couple of different ways how to do this as we go, but keep ALL MP for the final boss of each chapter. Each chapter has a "Big Bad", and you'll always need it.
