In Final Fantasy XIV, it’s not always that Eorzea needs a savior who ends up on other planets to prevent life from ending. Eventually, they need to settle down and start saving money for their next adventures. Learning how to make gil with gatherers in FFXIV is a safe bet to start filling any Warrior of Light's pockets.
While collecting materials and selling them is not as profitable as making gil with crafting in FFXIV, it is a cheaper method to start the path for your first millions in the game with Botanist or Miner. Unlike crafting, it’s possible to follow some of the tips listed here even with a low-level character.

How to make gil with gatherers in FFXIV
Earning money with gatherers is pretty simple and it boils down to finding a material that is selling well on the market board, finding their location, and collecting them. In case you want to know which items are worth collecting or not, it’s important to run a quick search on the market board or you can use tools like Universalis.
Collecting materials from legendary nodes
The most lucrative method to earn money with gathering is to focus on legendary nodes. These are special nodes where you find Folklore items and, unlike the regular items, they appear only twice during an in-game day. Many endgame recipes require these materials, allowing you to sell them for pretty high prices.
These items tend to sell well, especially when the recipe is new in the game because it takes a considerable amount of time to collect them. If you have the time – and the patience – to farm legendary nodes, you'll find a solid source of gil. However, this is not for everyone. Collecting Folklore materials requires high values of perception and you will need to invest in your gearset and melds to meet the requirements.

Getting materials with purple scrips
A good way to earn gil in FFXIV is selling unique materials needed for crafted sets of gear, pots, or food that you can only obtain by exchanging gatherer’s purple scrips for them. The Disciple of the Land and Hand classes are the only ones that have access to the Collectable system, allowing you to complete turn-in missions and receive purple scrips as your reward.
Farming collectables to earn enough purple scrips to exchange for these materials might seem like a longer process than other methods but it’s extremely worth it. Unlike legendary nodes, you don’t necessarily need to have the best gear for your gathering class to farm some collectables. In addition to this, these types of materials will always be in demand. Just search recipes for the top gear/food/pot to know which material you should spend your purple scrips on.
Selling Gatherer’s materia
Most types of materia are usually good investments when it comes to selling items on the market board. There are two easy ways for you to get Gatherer’s materia to sell. First, exchange white and purple scrips for them. If you’re already doing the previous method of farming collectables to get materials, you can start using the same scrips to get materia instead.
You can also gain materia by extracting them from pieces of gear you have spiritbonded. As you use pieces of gear, the percentage of spiritbond with them begins to rise. Once they reach 100% you can choose to extract a materia, and since this process doesn’t affect the equipment, you can constantly repeat it. Using Superior Spiritbond Potion can help you to speed up the process.

Selling secondary/low-level materials
The positive side of investing time in gathering is that you don’t need to look for the rarest and most expensive items to collect and sell for you to earn gil. While recipes require timed materials from legendary nodes or items you can only acquire by farming purple scrips, they also need other ingredients.
These are usually more common and sold cheaper than the aforementioned materials on the marked board. But, by focusing on collecting these, you can have a solid source of money, because many players who focus on crafting endgame items don’t have time to spend collecting secondary materials like these and they would rather buy them. Farming them and selling stacks of 99 items is a great option if you are still in the process of leveling up and improving your gear.
