Hint: Easy level up:
After you complete the Temple of Pyrynn and the two ship fights, go in the back way to the room before the magma walkway. Run up and down the room fighting monsters. This is also a good way to level up magic. You can get Moonberries at the end of fights, based on a random drop.
After you complete the Temple of Pyrynn and the following battles, heal and go in the back entrance. Go to the room after the magma walkway and run up and down the stairs. You will fight a group of Salamanders. Vyse can kill one in one hit, as can Drachma. Have Aika and Fina attack the same one, and it will be killed. They also seem to drop quite a few Moonberries.
After you go through the Dark Rift, you will be able to go back. After you finish off all the tasks and have to go around the world, go back to the Dark Rift then go to the exit. You will see a large black Elooper which is stronger than Ramirez. Battle it and automatically use Vyse's Skull Shield, Aika's Blocking Magic special, Drachma's Spirit Charge, and have Fina Focus. Repeat until you get the Prophecy Crew special and use it. Keep doing this until it dies to get 7,000 experience points.
Hint: Secret specials:
You need the Delpinus and at least five crew members to get these specials. Get your SP (spirit points) in battle to full and a crew SP icon will appear next to the item. This enables all of your active crew members to attack. Repeat these steps to get another special. You need all four people alive for this to work. This one combines the strength of all four people, and is the strongest special in the game.
