Final Fantasy XI Ninja Guide
At first, you’ll be fishing for actual fish and items like Rusty Buckets to sell for gil or use for food bonuses. As the game progresses, however, you’ll be using fishing for another reason–to aggro mobs.
After Level 40, this is what you will fish pretty much exclusively for, and in places like Sea Serpent Grotto you can fish to your heart’s content and stack items from one particular mob for a good, solid income supplement or raw materials for crafting.
13.5. Farming
Hunting monsters in FFXI is called farming, and you can stack items and sell them in bazaars or auctions, or use them for crafting. Not a whole lot of money in farming, but you’re going to be killing monsters anyway and you might as well make some gil at it. Tailor your kills so items will stack and fetch more money at the AH. Generally Goblins, Quadavs, Yagado and Orcs will have the most gil and the most expensive items on them.
At the early levels of the game concentrate on stacking items from the same mobs, which will give you the same amount of XP each time. Sell your stacked items at auction and learn crafting with them.
As you advance you will want to go to your local AH and find out which items are going for the most money. Post Level 20, you will begin hunting monsters almost strictly for XP and selling item drops for gil. You will also need to gain more raw material for crafting because between Level 20 and 30 is the time you need to work the hardest to advance your craft skills so you are not left in the dust at the high levels of the game.
Post Level 50, you will be making most of your gil from AF Quests and hunting NM’s. Killing regular mobs will no longer be very profitable or give you very much XP. Be selective, and try to target only NM’s or quest monsters.
Once you go to Dynamis, however, the drops will become better and better and you will, in a way, be back where you started in the game–making good gil from mob drops and stacking items like there’s no tomorrow. You can make up to 20,000 gil easily in Dynamis, and if you kill mobs that drop things like 100 Byne Bills or the Bomb Core at Level 70+ of the game, your gil will increase exponentially.
