Quick Links
There are many treasures to be found in the land of Aladiss inAtelier Yumia: The Alchemist Of Memories & The Envisioned Land,but you won’t always have an easy way to them. They’re often locked inside some ancient ruins that only reveal themselves to the worthy, or to those who brought the right keys.
And the Treasure Troves can encapsulate this concept almost flawlessly. You’ll meet them many times throughout the journey, but you won’t always be able to immediately put your hands on its hidden goods. But once you know where they are, you can always come back later for some profit.

All Lacuna Treasure Trove Locations
You’ll be able to find up tofive Treasure Troves in Lacuna,the least of all regions in the game. As usual, they’re represented with the “?” icon on the map until you reach them for the first time and give them a unique icon. The checkmark turns pink once you open the Trove.
Fortunately, it’ll be much easier to find them all this time than in other regions, but you’ll still need enough Keys to open them. You might need tobacktrack to other areas to search for Keys if you’ve been opening all Troves in the game so far,so be warned.

How To Get Treasure Trove Keys
Each Trove you open requires one Treasure Trove Key, which is immediately consumed.These are easily found around the many ruins you’ll come across throughout the game,usually inside chests locked behind puzzles.
You’ll find plenty of them innamed ruins(such as the ones visited during the main story), butnameless, lesser ruinsaround the areas could also have a few of them, so pay attention to all chests on the way. If you wish to unlock every Treasure Trove in the game,you’ll need to find all Keys available,so keep your eyes open to them.
If you complete half of the Auruma Pioneering Effort tasks, you’ll get access to theRelic Finder Recipe. The Relic Finder reveals the location of nearby Treasure Chests. They can potentially have some Keys, sothis is an essential tool for full exploration.
