Description

Complete Materia in Final Fantasy VII Remake and "Episode INTERmission". When equipped, it increases the user's MP by a percentage: 10% at first level, up to a 50% increase at level 5.

Use[]
MP UP materia provides a percentage-based boost to a character's MP. Multiple MP Up materia can be equipped at once to boost up to double a character's base MP. Equipping MP Up materia allows a character to cast far more spells in battle, and can be useful if a character has spare slots. The main drawback of MP Up materia is that, as it takes up a materia slot, it ends up occupying a slot that could have been used for a 
Magic Materia.
MP Up materia should be given to whichever character is casting spells most often. Aerith has the highest MP of the party. Due to her Arcane Ward and her high 
Magic, she will also be casting spells most often, making her ideal to prioritize MP Up materia for. As it is percentage-based, she will also gain the biggest increase from it. Cloud has the second-highest magic attribute, meaning that if a player is using him for spellcasting often, he also gains a priority. Tifa and Barret have the second-lowest and lowest MP pools respectively, meaning that if a player is using them to cast spells often, they are viable choices for the materia. However, this does not play well to their strengths, and players may choose to instead prioritize giving MP Up materia to Cloud or Aerith, using Tifa and Barret for non-spellcasting roles.
MP Up materia can be useful in hard mode when characters' MP is scarce.
In "Episode INTERmission", MP Up is less useful on Yuffie over other stat-boost materia, as she can already do magical and elemental damage without Magic Materia. She may need more MP for healing and for reviving Sonon Kusakabe in hard mode, though, where item-use is prohibited.
