How to Make Gil: Guide by Darkhavans

Introduction
Making Gil can be extremely hard, and most players have a lot of trouble with this pre-75. I have had a lot of experience and luck with making Gil in my FFXI career, and know hundreds of secrets and strategies; some I will share, others will remain secrets that you get to figure out yourself. There are hundreds of ways to make Gil in FFXI now, many more than a few years ago. The Treasures of Aht Urhgan expansion brought tons of ways to make Gil. This expansion has simplified Gil making for me, I'll tell you how later in the guide. Like my Farming Suggestions guide, this will have information added to it periodically, and you may add your strategy if you wish, but please format correctly and use correct grammar/spelling.

Farming

 * Description: No, this is not Gardening, farming is a slang-term to describe the repetitive killing of weak monsters to get drops that can be sold for money. This is one of the most popular ways to make money, but also the least fun and most dreaded.
 * Popularity: Very High
 * Productivity: Very High, dependent on job/level/area.
 * Profits: 5k-100k+ an hour. Again, dependent on job/level/area.
 * Level Required: 1-75, there are areas to farm at any level.
 * How-to: Farming can be done at any level, in almost any area, with almost any job. Since you will be killing monsters for their drops, a Thief sub-job is normally used, as you get the Treasure Hunter trait at level 30. This is a very basic strategy, but you should do some research to find good monsters to kill. Some popular monsters that are farmed are Crawlers and Bees

BCNMs

 * Description: Another popular strategy. These are Burning Circle Notorious Monsters, or BCNMs. You can find rare items that sell for quite a bit of money in these areas.
 * Popularity: Very High
 * Productivity: Greatly Varies, you could die and loose the BCNM, or just get crappy drops, therefore wasting time and Beastmen's Seals.
 * Profits: Greatly Varies, you may end up getting 10k in drops one run, and 5 mil in drops another run.
 * Level Required: 20+. Leveled capped battles at 20, 30, 40, 50, 60, and 75.
 * How-to: Firstly, find out which BCNM you want to do, to find a list of BCNMs you can do, just click on the BCNM link. You will need an orb to enter the BCNM, there are different orbs for different level caps. The amount of Beastmen's Seals required for each BCNM corrosponds with it's level cap, so a level 40 cap would cost 40 seals. You can obtain these orbs by trading Beastmen's Seals to Shami at H-8 in Port Jeuno.
