Yason-Roven Plains battle
After finding Reith and exiting the cave, you will be in Yason-Roven Plains. There is a battle in this area that may be confusing. Use the following steps to complete it. Instead of starting the battle with Calintz slashing away at the Blast Worms and Orha, just have Reith run North on the screen towards the cliff. In other words, get Reith as far away as possible from Orha. If you are feeling up to the challenge you can also defeat the Blast Worms and Orha, but running is best.
