Sydyru Bone

Sydyru Bone was a Legendary Crafting Material in Diablo III. It has a character level of 1, is account bound, and has a maximum stack amount of 1000. The bone was required to craft the Sydyru Crust bow. As of patch 2.0.6., the bone is not supposed to drop anymore (occasionally drops on PS4 due to a bug). Existing bones can be sold for 50,000 gold (75,000 on PS4).

It could only drop from the unique Carrion Bats:


 * Sicklefang (Carrion Farm event)


 * Glidewing (Cathedral Level 1)


 * Firestarter (Cathedral Level 2)


 * Hellscream (Unknown Depths)

Nothing attracts the ol’ flying flesh eaters like the bones of demons.
