- Obtain 99,999,999 gil - In order to properly grind out 99,999,999 gil, you will require as many All Materias as possible, the W-Item Materia, at least two Elixirs, equipment with Double or Triple Materia growth rate, and access to the Northern Cavern.

All Materia is sold in infinite quantity in the shop at Fort Condor in Part 2 onwards, after the battle with Shinra. Failing the Huge Materia battle mission, however, causes this Materia to become missable. Buy as many All Materia as you can to fill as many equipment slots possible.

The W-Item Materia can be found towards the end of Part 2, when the party infiltrates Shinra. In the Sector 8 Tunnel, after defeating the Turks, continue all the way south to the very end of the tunnel. Once you reach the end, you will find a save point and the W-Item Materia on the floor. If you missed this Materia during the initial raid, it can be excavated from the Bone Village. However, the chances are very low, and it is a frustrating process, so be sure to pick it up in the tunnel.

Now, you must take full advantage of the W-Item Duplication glitch. Specifically, you must duplicate as many Elixirs as possible. To do the W-Item Duplication glitch, equip the W-Item Materia onto a character and enter a battle. Select the W-Item command, and then select Elixir (or whatever item you want duplicated). A list of characters will appear to use the item on. Cancel out, and your item will be duplicated. Select the item again, cancel out of the character list, and it will be duplicated again, and so on. Duplicate as many Elixirs as you can.

Finally, head to the Northern Cavern. Equip the Apocalypse Sword on Cloud and the Scimitar on Cid, and fill as many Materia slots as possible with All Materia. If possible, equip the third character with a Double Growth weapon and fill in any remaining All Materia into its slots. Enter the swamp area of the Northern Cavern and wander around until you begin entering battles with Magic Pots or Movers. Once you’re in the right area, place down your save point and begin to grind for AP.

To get the most AP and EXP, seek out the Movers and Magic Pot enemies. Movers come in groups of three and yield a total of 800 AP each, for a total of 2,400 AP per battle, but no EXP. For the Magic Pots, simply use an Elixir on the Magic Pot and it will become vulnerable to attack. Do not attempt to attack it before using an Elixir. Once you defeat it, you will earn 8,000 EXP per defeated Magic Pot and 1,000 AP per defeated Magic Pot. AP earned in battle can be tripled with the Apocalypse Sword or Scimitar.

The goal is to master as many All Materia that is needed to obtain 99,999,999 gil. When an All Materia is mastered, a new one is birthed and can be mastered anew. A mastered All Materia can be sold for a whopping 1,400,000 gil, and it is rather fast to master using Magic Pots. Assuming you begin with 0 gil, a total of 72 mastered All Materia will need to be sold to reach 99,999,999 gil.

Enabling Turbo Mode while grinding out AP to master All Materia will significantly reduce the amount of time it takes to reach 99,999,999 gil.
