How to Get Easy Gil in Final Fantasy XII

Do the first hunt mission to gain money fast at the beginning of the game.

Steal from the Cactoid in the Eastern Sands. Usually, you will get a Cactus Fruit that sell for about 77 Gil each. Occasionally you can steal a Broadsword that sells for 200 Gil.

Gain access to the Salikawood after the Mosphoran Highwaste in Nabradia.

Go into the section of Salikawood called Quietened Trace. This is located North. You will find a Gate Crystal.

Save the game and choose one character. This character should be able to equip the Thief's Cuffs accessory.

Go into the Grand Bower section of Salikawood.

Steal from the Giant Bomb Boss, and exit the area.

Restore HP and MP at the gate crystal and repeat as much as desired. There are 3 items you can steal from him. These are the Bomb Shell that sells for 900 Gil, Fire Crystal which sells for 100 Gil, and Bomb Fragment that you can sell for 2,000 Gil.

Defeat the Zeromus Esper located in the Stilshrine of Miriam. This is not part of the storyline and is a side quest.

Reenter the Throne Of Veiled Gods and chain kill the Dark Lords. These Dark Lords drop Blood-Darkened Bones. After having a big chain of kills, each Dark Lord can drop up to 4 Blood Darkened Bones. Occasionally you can get Dragon Mails from them, netting you a significant amount of Gil when sold.

Use the Teleport Stone when you have attained 99 bones.

Go to the nearest area with a store and sell your 99 bones, Dark Crystals, Pebbles, Capricorn Gems and other things. The Blood Darkened Bones sell for around 1,400 a piece. Do not sell the Teleport Stones.

Leave and return to the map using the Waystone 3 times. This will respawn the The Dark Lords so that you can repeat this process again.
