Golden Sun: The Lost Age Tips

Yampi Desert
There is an easy way to get through Yampi Desert w/o going through Yampi Desert (I think this will work with all deserts). NOTE: you need sand to do this. First, you go right next to the edge of the desert, not far enough so that you've entered, but your on the sand. Cast sand. You can now go through Yampi Desert w/o actually going through it. You can stop sand once you've passed the entrance. It is probably faster.
