最も獲得が難しいトロフィーのひとつ。 まさにアイテムマスター！ おや？ だれかこの図鑑を必要としている人が……？ 一晩だけ貸してあげますか？
Collector's Book Complete
(One of the most difficult trophies to earn. You are surely an Item Master! Oh? Is there somebody who needs this book…? Could you lend it just for one night?)
There are 1238 Collector's Book entries. You can find the Collector's Book in Rita's hut once she joins your party. Some items are only available through synthesis. Never sell any items, especially weapons. Some weapons can be synthesized twice, so be careful with synthesis. To complete your Collector's Book, you need to do almost every side quest. If you start a new playthrough, make sure you select the option ??????????(Collector's Book) from the Grade Shop to inherit your Collector's Book progress.
Please refer to the Collector's Book thread for a list of items and how to get them.
