Hidden Spirit On Ferry- After you have beaten Nepty and have been transported back to Larapool, make your way back to the ferry that originally brought you there, get on the ferry and ride it three times. On the third trip, stay in the cabin and move up to the crates on the right. A "?" will appear over Brian’s head, signaling an invisible spirit element.
Free Refills- Go to a hotel and say you will stay the night. Then, when at the saving screen, hit B to escape. You will now have full health. Also remember that bread and wings are free.
Avoiding Attacks- When an enemy uses a physical attack (ex: Rock, Cutter), quickly begin moving your control stick as soon as the spell is cast. You'll be able to dodge the attack before it gets to you.
Spirit in all Elements- When you find a spirit and that little screen pops up, if you press all four C buttons at once it gives you a spirit in all elements! Like four for 1! But be careful they must all be pressed at exactly the same time or it goofs up and you don't know what you will get.
