A guide to finding Trails in the Sky SC's hidden items Gambler Jack

Update from the author : "I apologise for a mistake I made regarding vol. 10. I have corrected it to "after Carnelia Tower“ instead of “after Amberl Tower” now."


The much-anticipated Trails in the Sky SC was finally released on Steam and PS Vita released three weeks ago. This series is famous for its many missable items and quests. In the first chapter, there was the Carnelia book series. In this chapter, they are the Gambler Jack books. This will be a one-stop guide for those wishing to get all those pesky Gambler Jack volumes once and for all.

The Gambler Jack volumes are necessary for you to obtain two of the strongest weapons in the game. For those playing on Steam, there’s the achievement. The books themselves are a pretty good read as well.

Once you have collected all of them, you can give them to Baral on the 3F of Grancel Bracer Guild during the main quest “Danger in the Capital” at the end of chapter 8. I took a screenshot since he’s not that easy to spot.

After handing him all the books, he will give you the Zemuria stone in return.

In the final chapter, in the Residential Block – Cradle’s west building, talk to the terminal to receive Data Crystal Z.

After receiving Data Crystal Z, proceed to the south building and talk to the terminal. Choose “read crystal”, and you will receive a second Zemuria stone.

This is a map of Residential Block – Cradle. I have circled in red the two buildings you need to visit.

Return to Arseille and talk to Professor Russel. He will use the Zemuria stones to make two of the nine strongest weapons in the game. Do choose wisely as you cannot change the weapons afterward.
