Switch Weapons Frequently
A new element introduced in Final Fantasy VII Remake is the unique weapon abilities. New weapons can be hard to come by in this game, but when you do get a new one, consider switching to it even if its stats may not seem that great initially.
Every weapon specializes in a different area; for instance, the Nail Bat has pretty poor stats, but boasts a high critical rate once you upgrade it, which can make it quite a devastating weapon in combat.
In addition to that, every weapon comes with a unique ability that you can master the more you use it. Once mastered, you’ll be able to use that ability any time, even when you have a different weapon equipped. It’s definitely worth experimenting with all the weapons you find just for those abilities, as they add a lot of utility to your characters.
