Ok, I've seen a whole lot of posts recently about people and their in-game fiscal concerns. I'm having them myself. There's just not enough ways to make money. So, I figured it was time to post a guide for you all. I can only contribute part of it, but that's where the rest of the people posting here come in. I'd like to come up with a decent gil making guide. I can only really post about how to start making gil in windurst, so you guys will have to fill in the rest. With a little help we could all be a heck of a lot richer without lowering ourselves to the point of people who buy gil with IRL money.
(By the way, this isn't a playing guide; it's just my methods to help friends make money in the game)
Here goes...
IN WINDURST:
LVL 1-5:
First, obtain the quests "The Postman always K.O.'s Twice" and "Paying Lip Service." For now these are the best money making quests to go on.
Next, go to the gate in port windurst and get signet cast on you. Proceed outside and slay everything within the limits of your skill. Try to keep a watch out for things which check as even or tough. At this low of a level an even match tends to not really be even. Just kill everything you can, and when your inventory gets full, run back in town and drop it off in your mog safe, then go out and keep hacking away. I never really bother with buying new equipment until around level 5. Once you reach that point, head back inside the city, go to your moghouse and unload the last of your loot into the mog safe. Now, look at the safe and its contents. Look for stacks of twelve. You may want to write down what you have stacks of and run to the auction house and check to see what's selling for the most. Try to ONLY sell stacks of things at this point. Selling single items really won't benefit you too much, so you might as well let them sit in your mog safe until you have a stack of 12 (there are exceptions to this).
Then, pick the 7 which you believe will sell the best, and go place them up for auction. Now would be a good time to go drink a beer or something, watch some TV, what have you. Come back in a little bit and see what's sold. (Or you can skip to the first part of the next section and get some quests).
With the money you've earned, buy yourself some new equipment. Drop the old stuff (old sword, etc), it can't be sold for the most part, so don't waste your time on it. Now the real money making can start.
LVL 6-10:
Before you go hunting, you're going to want to start the missions:
Creepy Crawlies
Mandragora Mad
These two quests will be extremely valuable until you're ready to go up to Tahronghi Canyon.
Ok, you're going to want to get signet recast on you, and then head back out into west sarutabaruta. Now, venture out slightly farther. You should try to hunt almost exclusively for Crawlers, Goblins (which check for a decent challenge), and Carrion Crows. Crawlers drop Crawler calculi and silk thread. A stack of silk thread sells for about 10000 in the AH. 3 Crawler calculi are good for an easy 600 gil at the Dhamel ranch. Carrion Crows are only good for fire crystals (in my personal opinion). Once you have a few stacks of things, run back in town, check the safe to see if you've completed any stacks, and go sell your booty at the AH. Buy some new gear, and head back out again.
By now you should be able to take on Mandragora and Yagudo. The main target should be the mandragoras, but yagudo are occasionally good for dropping spells which can be sold on market. Just about everything which mandragoras drop can be used in the Mandragora Mad quest, so take advantage of its repeatability and earn some gil.
If you fight some yagudo, occasionally they can drop yagudo necklaces. Use a wind crystal and a single yagudo necklace to yield a set of 3 grass threads. The threads are worth more in a stack than the nonstacking yagudo necklaces, plus you'll get to build up your cloth working skills.
Pretty much stick with this method until you can take out just about everything in West Sab.
You may want to run over to East Satura Baruta and try some things there. Be careful though, I noticed a big increase in difficulty when I started there. However going over to east sab can help you earn a little more gil from the Postman quest.
When you think you're ready to move on, head back into town.
Now is the best time to buy pots to plant plants in. You don't have to worry about seeds for now, but buy a variety of pots. They're decently priced at around 1k each, so try to get as many as you can (not more than 10 though).
Lvl 11-?
Get signet cast on you, and head to tahronghi canyon. Be careful as some of the enemies are rather tough here. For now you'll want to stay in the pass until you feel secure enough to venture out into the open plains.
The biggest money maker which I've found here are Strolling Saplings. Kill as many as you can. They drop the second best money maker in the windurst area, bags of herb seeds. On my server, Garuda, a stack of 12 bags sells for about 8k gil, which is decent considering it’s a fairly common drop. You may get other types of seeds dropped such as fruit or grain. Take these seeds home and plant them, and feed any spare crystals to them.
This is where I am now with my gil making scheme. Now is where the rest of you come in. How do you make gil in different areas of the game? What do you think are the best things to hunt/best hunting spots? Try to contribute what you can.
