Where to Find Crystal Marrow

If you are looking to farm Crystal Marrow you’ll have to leave the shores of the mainland. As it stands, the only place to find these plants are on the islands of Inazuma. The largest cluster of them is found on the giant bones on Yashiori Island. Gathering all of these alone will net you a large percentage of all the available nodes. The other most obvious place to farm Crystal Marrow is near the outside the entrance to Tatarasuna.

There are 49 Crystal Marrow on the southern island with an additional 13 by Tatarasuna. Gathering all of those would be checking every single node on the map, leaving you with 62 marrow per refresh. How quickly you accrue the resource ultimately depends on how much time you’re willing to spend getting the harder to reach nodes.

There is likely somewhere you can purchase Crystal Marrow as well, but we’re still exploring the new Inazuma region and Genshin Impact 2.0. We’ll keep you updated should we find more sources of the material.

Remember, the crystals will respawn around every two to three real-world days. Because of this, I recommend hitting both areas areas. This will maximize your farm, reducing the amount of time spent waiting for them to refresh.

Crystal Marrow Uses

At the time of writing this, Crystal Marrow will primarily be used for character ascensions. Right now there are no active characters who require this material for ascension. However, according to datamining the upcoming 4-Star Sayu will use them. We have not discovered any recipes that call for Crystal Marrow as of yet.

It takes 168 Crystal Marrow to reach Ascension 6 for a single character, so I recommend you start farming early. Even if Sayu isn’t available right now, there’s always a chance you could pick her up in the next banner. It’s also a safe bet that miHoYo will release more characters that need this material so it doesn’t hurt to gather some now.
