The EXP Plus Materia can be bought in the Gold Saucer's Wonder Square after the party has the Highwind for 2000 GP. Only one can be obtained this way, meaning it must be mastered for the player to obtain multiple.

EXP Plus increases the amount of EXP earned after battle. This can be very useful for level grinding, and as such is useful to equip on any character. This can be useful when in Cactus Island fighting Cactuer, and later on, many of the enemies in the Northern Cave.
The main drawback to EXP Plus is that only one can be obtained without mastering one. This means that only one character will benefit at a time, so if the player wishes to level their party evenly, they will have to pass it between characters.
