Stolen Tears

Go to the Eclipse Tribe at Dadaupa Gorge

First things first, you need to get to Dadaupa Gorge. The quickest way is to teleport to the Eagles Gate Domain. From there, just follow the path heading west. When you get close, the camera will automatically pan, showing you exactly where the chest with Dvalin's Tear is hidden. You'll notice a group of enemies right in the middle of the area. Be prepared to face a boss-level Wooden Shield Mitachurl, an Anemo Samachurl, and a Cryo Abyss Mage. Your best bet here is to use Pyro attacks – they work wonders against this mix! If you can, try to take out the Anemo Samachurl first because it can really make fighting the others a hassle. If you decide to drop down into the central area to fight, you'll have to deal with even more enemies, including another Mitachurl and some regular Hilichurl Shooters. Keep an eye out, there are also a few chests scattered around: one on the southern tower, another behind some rocks in the central area, and a couple more tucked away in the huts.

Open the chest to obtain Dvalin’s Tear

Once you've cleared out the enemies and you're ready, it's time to grab your prize. Climb up the ramp and open the Precious Chest. Inside, you'll find the final Teardrop Crystal, along with some other goodies. Opening this chest marks the end of this quest!
