Quick Links
Throughout the many ancient ruins found across the Aladiss Continent, one might be lucky enough to stumble across treasures forgotten by time itself. InAtelier Yumia: The Alchemist of Memories & The Envisioned Land, those treasures are one of your main goals while fully exploring a region and can lead you to many otherwise unobtainable riches.
By interacting with the Treasure Troves, one can unlock them if they have the right key, and there are plenty of those to be found across this tragedy-struck continent. If your exploration instinct speaks louder, you can claim those treasures by yourself, as long as you know where to look.

All Ligneus Treasure Trove Locations
you may find a total of12 Treasure Troves in the first region of Ligneus.They are often placed next to Shrines of Prayer or other ruins, or might even be surrounded by fierce monsters, so beware.
There’s no correct order to open them, so go for whichever is nearest for you. Opening a Trove requiresa Treasure Trove Key.

The final two Treasure Troves in this list cannot be accessed right away andare only available after you explore a certain portion of the Sivash region. The quest Village Exploration will show you the way to the previously inaccessible zone in Ligneus.

How To Get Treasure Trove Keys
The keys to these ancient temples can be found byexploring the continent’s various ruins. You’ll usually get a few of those inside chests in the Manabound areas you clear during the main quests, but many of them are found inside the simple nameless ruins around the map.
A good example is theDux Lighthouse, where you’re able to find keys both inside the main ruins and also in the nearby smaller ruins, hidden behind a puzzle. If you explore enough, you’ll often end up with more keys than Treasure Troves to open.
If you end up needing some extra keys, you can alwaystake a quick trip to any ruinsto see if you missed anything. If you don’t see a pink checkmark underneath the ruin’s symbol on the map,it means there’s still something to be found in there,and that something might be a key.
