I want to give some advice for completing the Journals since some can be easily overlooked.
- 'Rabbit' in the 100 Acre Wood Command Board will be registered in the Journal only when you touch a special panel
- Three unique commands in the Command Board can only be obtained outside the Mirage Arena: Ragnorak (Land of Departure), Meteor Shower and Focus Block/Barrier (Castle of Dreams)
- Minigames such as the Illusion challenges and the Pot breaking from Olympus Coliseum
- D-Link commands have two finishers and you need to at least use both of them once
If you're also going for the Trinity Archives, you need to purchase every item from the Mirage Arena's moogle with each character.
