After you find all of the Ancient Stone Tablets, you have a new objective. This guide on Where To Find Strange Jade Plates In Genshin Impact will tell you where to track down these special Jade Plates at the various ruins scattered throughout the region.
This is the second part of the Treasure Lost, Treasure Found quest. The first part has you searching ruins for Ancient Stone Tablets. Once you’ve found them all and returned to the inn, you discover that there are special Jade Plates hidden at various ruins in the area. It’s a huge area to explore, so let’s get to it. The very first one is marked on your map, easy to find, so you shouldn’t have any problems there.
Jade Plate Location #2
The first one, after the initial one, can be found here. It’s on some ruins that sit atop a cliff-like area near the water. It’s near the fast travel point. It’s surrounded by vines and fire enemies so prepare for that ahead of time.
Jade Plate Location #3
A short distance North East of the nearby dungeon entrance.
Jade Plate Location #4
The final one is also quite close to the original ruins, and right where you found one of the Ancient Stone Tablets.
Final Ruin Location
There is another one near the original ruins, near the large pool of water. This one is unique, when you interact with it Paimon says the mechanism won’t activate, maybe it takes some sort of special approach. It’s not related to this step of the quest. You have to find all 4 Jade Plates and then Researcher Soraya asks you to locate the final ruin. Defeat the three large enemies to reveal the entrance.
