Golden Sun Hints

In Suhalla desert when you find the red tornado (before or after youve beaten crossbone isle)[this can help prepare for deadbeard] dont use douse on the tornado! instead let it sweep you away you will be bought to an uncharted island you will see forest areas and a gap in a large rock go there now go backout you will see the red tornado use douse on it and fight the huge lizard and you will recieve 1360 EXP 6400 Coins and a potion now do not worry go back in the gap area and exit again the tornadoe will be there again repeat the process or leave your choice also if not done already complete the dungeon on the island be prepare the boss has about 10,000 hp and is weak against earth hope this helps

Hint: Warp To Last Save
From a cold start (i.e., turned on your GBA), you can start at the last town you visited by selecting to continue your file, then hold L + R + START + SELECT.

Hint: Crossbone Isle
In order to get to Crossbone Isle, a place not listed on the map, go to Vale Cave after you have the Psynergy, Lift. Explore the cave and find the Halt Circle. Then go to the Suhalla desert to find the red tornado near where you found the moving tornado. Use Reveal to see footprints. Keep using Reveal until you find a hidden stone platform. Jump onto the platform, and across the ledge there will be a cave. Get through the small cave and you will end up behind the red tornado. Use Halt on the tornado and you will be transported to Crossbone Isle. The enemies here, including the boss, are tougher.

Hint - Monster Farming (Tempest Lizard)
I found out that if you take the red tornado to Crossbone Isle then walk back into the tornado when you arrive at the island, you can use "Douse" on it as you would normally to fight the Lizard at that beach where it's waiting instead of at the desert! After you've won, it disappears. Don't freak out! Just walk back into crossbone Isle (the area, not the actual island) and walk out of it again, the red tornado is there again! So you can keep on killing it at least until your party becomes downed. This will gain you over 1000 experience points, around 2400 coins and a Potion each time you defeat it! This should work, but save before you try it (I did) and save again when your'e safely back at the desert. Try killing it by using level 4 summons and then a couple of Ragnaroks!
