In West Karana's, leaving the large wooden bridge that leads into the zone, go right. Follow the river to the barbarian fishermen village, and walk out straight into the water, swim down, and you'll fall for about 7 dmg, and be in an underwater cavern that makes it look as if you were walking under water. This is fun if your bored. It used to raise your swimming skill by running back n forth in the cavern, but I maxed mine and wouldn't know if that still works. Enjoy!
