Final Fantasy 7 Remake Upgrading Weapons
You can upgrade weapons to acquire new skills when wielding them in battle. You can do this by going into the menu and selecting Upgrade Weapons.
Skill Points (SP) are expended when upgrading weapons. These are acquired whenever a character levels up or by using combat manuscripts found throughout the game.
Unlocking Weapon Upgrades
To upgrade weapons, you must have reached Chapter 3 in the main story.
How to Upgrade Weapons
From the Upgrade Weapons menu, select a weapon you wish to upgrade. This will open up the weapon core screen, allowing you to choose skills you wish to unlock using your available SP.
Acquiring skills of a weapon’s core unlocks sub-cores that allow you to obtain more powerful skills and even additional materia slots. Because of this, even weapons acquired early on will be as strong as those obtained later in the game.
How to Get SP
As mentioned, SP can be obtained whenever a character levels up which can be slow and time-consuming when at high levels. It is recommended to play the game on Hard Mode which grants x3 experience and x2 AP when defeating enemies.
Use Combat Manuscripts
Another way to get SP is to get combat manuscripts. These key items instantly grant a character a fixed amount of SP when used.
Reallocating Spent SP
SP used to unlock weapon skills can be reallocated by clearing the side quest Chadley’s Report. This unlocks Chadley’s Reset Upgrades service that allows you to regain spent SP and allocate them again as you wish for a fee.
