Where to Find Crystal Bone Marrow in Genshin Impact – Farming Locations and Routes
Crystal bone marrow is an Inazuma curiosity in Genshin Impact that has had no practical use so far.
What is Crystal Bone Marrow
This crystal contains a fraction of the power of the Tatarigami. When this material is added during smelting, the strength and stability of metals are significantly increased.
In Inazuma, Tatarigami refers to the remains of a divine being and the strange phenomena that occur around them. It is said that before becoming Tatarigami, the god who created the crystal bone marrow had many different names, one of which was Orobashi no mikoto. Orobashi no mikoto's body was longer than the winding coastline, and his voice was so loud that only the depths of the Dark Sea could swallow him up. Yet he, too, fell, as did Yashiori Island itself.
Where to find Crystal Bone Marrow
Like other ore variants scattered across Teyvat, Crystalline Marrow tends to grow around rocky outcrops. Most of the locations are around the center of Yashiori Island and the cliffs branching off from it, but there are also ore deposits to the west of the Kujo camp area on Kannazuke.
Location Crystal Marrow | Yashiori Island
Be sure to stay away from lightning strikes while farming ore on Yashiori.
Location Crystal Marrow | Island Kannazuka
Crystalline Marrow – Spawn and Craft
Just like other ore items, Crystalline Marrow respawns in a couple of days in the real world. There is no way to create your own ore yet, so you will have to wait until the update brings more features.
However, you primarily use Crystal Bone Marrow for only one purpose, so there is not much demand for large quantities of this ore at first.
What is Crystalline Marrow for?
Sayu uses Crystal Marrow during all stages of his Ascension. The later phases require 40-60 ore, so you won't be able to level up Sayu from 0 to 90 in one day.
If you have an excess of Crystalline Marrow left, it can be used in another way. Some Inazuma world quests require a dozen or more of these collectibles from you.
Future characters can also use Crystal Marrow, so it's worth waiting a while if your inventory isn't full.
