Have you written in it?

Did you outline the drawings to see what you're really looking at?

Make names of potential crafters from launch to keep tabs on their progress? Then eventually go back and finds them with an invite to a linkshell you're in?

Wonder why the contents of your artbook are upside down?

Make a handwritten list of all the recipes you learned?

Coordinates of places you gather from and what you get from those nodes?

Forgot that you had it?

Didn't get one?

Left it blank, because it was too delicious to ever use, so it can't be used?
