Raise White Magic level easily
This trick is useful to level up much needed spells such as Protect, Cure, and Shell. Go to a local residential area and stand directly outside your Mog House. Cast the desired spell on yourself until you run out of MP. You can also cast it on other players running in and out of their Mog House. Once you have run out of MP, run into your Mog House, replenish it, exit, and repeat. This saves a large amount of time from having to heal after casting. You can level up magic by casting the spell on yourself, despite if you already have the enhancement on yourself or have 100% HP. Keep casting and it will level up.
Easy gil
This trick requires two characters. When starting a new character, you are always given an Adventurer's Coupon. When given to the correct person, you will obtain 50 gil. Make two characters and have the character that will be your main character be in his Mog house (preferably in order to get to the Delivery Box faster) and have the second character go to the Auction House in which ever country they are in and deliver their "Onion" weapon and Adventurer's Coupon to the main character. You can use the Adventurer's Coupon repeatedly. When the main character has received the items, delete the second character and make a new one with a new coupon and weapon. As for the weapon, put it up on the Auction House for about 100 to 200 gil. You can repeat the process as many times as desired.
Whenever you get Crystals in battle, put them in an auction for about 100 gil each. You will make good money this way, or you can put them in your bazaar for about 50 gil each.
At 6:00 in upper San 'Doria, the Wood Guild opens. There, you can by Arrowwood Lumber for 7 gil each. They sell for approximately 100 to 150 gil each. Also, the Luaun Lumber makes a profit, but not as much.
This trick requires three party members in Bastok. Behind the lighthouse in South Gustaberg is a bush labeled as "???". There, you can trade a Quus to have Bubbly Bernie spawn. He is not very difficult to defeat and drops a Steam Clock. If you set the second person to Quartermaster and make him wait at the entrance to Bastok Mines, he can run into the auction house and send it to the third person, waiting at the Mog House in Bastok Markets. The third person should take the clock to Malene in the very northern part of the town. She will give you 500 gil per clock. You can repeat this as many times as desired. Note: You can only hold one clock at a time, but you can have as many as you desired inside your delivery box.
