Bone

Bone Dust
Bone Dust is a white powdery solid that is most commonly seen as the blood material from seemingly-undead enemies, such as Stevari and Hahmonvaihtaja.

It is generally very inert and does not react with most other materials.

Bone Wall
Bone Wall is the solid, static form of Bone Dust. It is only found in the Desert, being the material the giant skull is composed of.
