Final Fantasy VII Remake Intergrade Yuffie DLC - All Materia Locations

It's good to collect all materia's during these 2 chapters - you will need them for combat simulator challenges. I will note what they are and where you can find them. They are really easy to find and it's quite hard to miss them if you like the explore. This is still a linear experience, so you shouldn't have much issues finding them all.

The list is written in chronological order. What you miss you can find again when you unlock chapter select, and some materia's can be picked up only once, usually all that you cannot buy, which means some other common materia will be at that spot when you repeat the chapter. 

Chapter 1

HP Up
Abandoned Warehouse 2F
Near the start, after using the first elevator, simply find it on the other side of the Warehouse. You can use the other elevator (shoot it with shuriken to bring it down) to reach the top, where the materia avaits. You can also buy these at any vendor that sells materias, or in vending machines next to benchs where you rest.

Wind
Connecting Passageway
You will reach an open area where you need to climb the tower, shoot the crane to create a path and defeat 2 dogs at the other side next to the prisoner NPC. Don't go through the passageway next to him, instead go right and climb the tower there.

Mp Up
Scrap Boulevard
After the next cutscene here, find it in the short tunnel.

Warding
Residential Area
It’s in the area just northwest of Avalanche’s Base. Circle around it, enter the area behind, enter through the tunnel (you will find some kids and the teacher there).

Ramuh
Residential Area
You will need to talk to Chadley during this chapter for story purposes. He will open his VR Challenge. Before you leave Slums you will be notified about it (before you board the train), so you can try it then, you will be much stronger and you will have Sonon with you at that point.

Chakra
Residential Area
Second flor of the motel. First do the Old Snapper quest for finding six turtle flyers. One of the flyiers is at that floor. After that, climb back and check behing the dog.

First Strike
Abandoned Talagger Factory
Northeastern room of the Factory in Slums, where you found one of the turtle flyers. Destroy boxes there to reveal a materia.

Chakra (2)
Abandoned Talagger Factory

AP Up
Residential Area
Reward from defeating all Fort Condor players (minigame) in Slums. You can find the video guide and strategy topic in this trophy guide for help.

Prayer
Ward 3
When your reach the area with two Drake enemies, in the northwest corner, next to where you have to throw your weapon to stop the conveyor belt.

Elemental
Ward 1
On a platform in the middle of Ward 1. You will see it from the distance. You need to climb the fence to the other side, shoot the middle platform to spin it, then climb the same fence to the top, where you can then follow the path to find that materia. If you don't climb that fence to the top, you've missed it.

Magic Up
Perimeter Wall
It comes after a long section where you ride a platform and where you shoot boxes when you ride it. It's in the corner on the left side, before doing the wall-run.

Lightning
Central Maintenance Facility
Before you fight the boss, there is resting bench if you follow the southern path. The boss is in the center, if you follow the path east.
