Resist is a magic spell in Final Fantasy VII Rebirth. It is the provided by a max level 
Cleansing Materia. The spell applies the 
Resist, which prevents any negative statuses from applying.
Use[]
Resist can be cast by party members with level 3 cleansing materia, and only costs 8 MP to cast. It prevents all negative statuses on one party member for its duration, but does not remove any negative statuses that have already applied. Because Resist can prevent crippling statuses, such as 
Petrify, 
Toad, 
Sleep, 
Silence, and 
Stop, it can be invaluable in many battles. Resist can save the party the need to heal a status with 
Esuna, something that has a much greater MP cost.
Alternatives to Resist include wearing accessories to resist against statuses being applied in the first place, and equipping 
Warding Materia to prevent them. It is ideal that at the very least the party member with cleansing materia who will cast Resist (or Esuna) is themselves protected from negative statuses by way of an accessory or a warding materia pairing, but otherwise, these options are often not available due to how limited accessory and materia slots are.
Pairing Magnify Materia with cleansing materia allows a user to cast Resist on all party members at once. Because magnify is so rare, this is not an ideal use of magnify materia, but in some it can be a useful tactic.
