There are some ways to quickly gain AP in the Final Fantasy 7 Remake. One of these revolves around the Pedometer Materia. You need to gain AP in order to upgrade your Materia and thus the Pedometer Materia can come quite handy in such a situation.
How To Gain AP In Final Fantasy VII Remake
Once you reach Chapter 14 in Final Fantasy 7 Remake, you will be able to get to Aerith’s house. Once you are there, go and talk to Emyra to get information on the Pedometer Materia. You can find the Materia in the garden once outside. After equipping it, you will be able to target a step count that once completed will lead to a reward.
It is best to start working on it as soon as possible. Just equip the Materia on someone like Cloud and then forget it for a while. If you do enough running around and hit 5000 steps count, you will be able to reap the rewards. As mentioned before, you need to gain AP in order to level up your Materia and the reward for this task is an AP Up Materia.
Once you have completed the 5000 steps task, the Pedometer Materia will transform into Ap Up Materia. You can then use it to level up your Materia like the elemental spells and so on in Final Fantasy 7 Remake.
To use the Materia, put it in one of the linked slots in accessories or weapons. After enough battles, it will improve the linked Materia and you can change them and switch to a different one.
