The Cotton Robe Synthesis Trick is a very basic tactic that you can use to take advantage of some oversights with the buy and sell price of certain items. There are raw materials that you can purchase, synthesize and then resell, for more money than the initial raw materials are worth. You can use this trick to make easy gil early on in the game.

Process Overview

Start by purchasing:

• Wrist (130 gil)
• Steepled Hat (260 gil)

Then synthesize the two items into:

• Cotton Robe (cost 1,000 gil to synthesize)

Finally, sell the Cotton Robe for 2,000 gil which will net you 610 gil for each Cotton Robe synthesized!

There are numerous points in the game where you can utilize the Cotton Robe Synthesis Trick, including:

• Purchasing the Wrists during the first visit to the Village of Dali
• Completing the trick by purchasing Steepled Hats and synthesizing the Cotton Robes first visit to Lindblum
• Purchasing Steepled Hats when the team visits Summit Station at the beginning of Disc 2, purchasing Wrists later on at the beginning of Disc 2 at the Village of Dali and then synthesizing them in Treno
• Purchasing more Wrists in the next visit to the Village of Dali in Disc 3
• Completing the trick one more time at the end of Disc 3 (by revisiting other towns)

These various points are identified in each of the sections of the walkthrough guide as they come up. This trick is incredibly useful for earning a ton of gil fast within Final Fantasy IX.
