Gathering is one of the purest ways to make gil in Final Fantasy XIV: with no material cost, almost everything a Miner or Botanist pulls from a node is profit. The only real question is what to gather — and that's where most gil is left on the table.
A crafter has to buy or make ingredients; a gatherer starts from zero. Every log, every cluster of ore, every handful of herbs you collect can go straight to the market board. Because you have no cost basis, even modestly-priced materials add up fast when you're gathering them by the stack.
The mistake almost everyone makes is farming whatever's convenient — or whatever a months-old guide recommended — only to find the market has moved on and the item now sells for a pittance. Node value swings constantly: a mat tied to a current crafting meta or a fresh patch can be worth many times what it was a week ago, and vice versa.
The fix is to gather what's actually selling right now on your world. The Gathering tool estimates gil-per-day for gatherable items from live prices, so you can pick a route that pays instead of hauling back something that's crashed.
Gathering demand spikes with each major patch: new recipes, new housing items, and fresh crafting gear all need raw mats, and supply hasn't caught up yet. The first days after a patch are often the most profitable gathering window of the whole cycle. Prices then settle as more gatherers flood the nodes.
