Genshin Impact : Fragile Bone Shard

To obtain a Fragile Bone Shard, you need to find and kill Geovishaps at any level. Upon eliminating these ancient dragon foes, they have a chance to drop Fragile Bone Shard.

You can get these from two of the Geovishap family. You won't get them from Geovishap bosses—Primo Geovishap and Azhdaha.

The fastest way to get around is to use the Waypoints, travel around Liyue, kill everything in sight, and move on. The image below is where you can find Geovishaps in Liyue.
