No matter how great your game skills are you will need the Gils to get your equipments, armors, weapons and other items. Having the gears early in the game will help you advance to higher levels at a faster pace than others can. Here are some good tips to start your career in Final Fantasy XI.
This method can get you about 10k gil within an hour. You need to start with 1k to purchase a slime oil. After you've purchased the slime oil, bring it to an NPC named 'Unlucky Rat' in the Metal district of Bastok in exchange for a warp scroll. The scroll sells for about a good 7-10K. Seems easy? Well slight problem with this method is that you will need to have enough fame built up before the NPC will take your slime oil. You will be required to run around town doing low level missions to get your fame up. This is where it gets a little time consuming but 10k gil an hour for a lowbie is really good. You can also redo this quest by creating a mule account and transfering 1k gil to that character.
Just Badge Quest
The Justice Badge quest is located in Winhurt and will require 1 rabab tail and 4 onions to complete. you can buy the stack of rabab tail in the auction house for 50-100gil. Easy to do at low level. In the docks of Winhurst you will find an NPC that you can give the rabab tail to. He will give you the Justice Badge which sells for 500-2000 gil in the auction house. After receiving the bad, give him 4 wild ionions and you'll receive a scroll that sells up to 5000 gil. You can repeat this quest by using a mule.
A stack of first crystals can sell for 2000 gil easily over at the auction house. There are 2 good methods to collect fire crystals. The more commonly used method would be the usual beat the mob down and loot method. To start you need to be around level 7-10. You will need signet cast on you at your town gates. Head out North to Gusterburg where you will be able to find many vultures. You'll only want to kill the vulters and nothing else to conserve time. To the Northwest of San D'oria there is an area full of Orcs. The orcs drop a nice amount of fire crystals as well. You can probably average about 3 stacks in an hour. 6000 gil in an hour for a level 7-10 is not too bad.
The other method of farming fire crystals is by gardening. You start by buying a brass flower pot in the auction house, several vegetable seeds and some water crystals. You then plant the flower plot in your Mog house and put in the vegetable seeds. Feed it some water crystals, after 1-3 days you will have 17 fire crystals come out of it. You can have up to 6-8 flower pots per house, you can easily make 20-30,000 gils every 2-3 days. It only takes a few minutes to purchase the accessories and to plant them. It's a wealthy short term investment. Money growing on trees is the way I think of it.
