Bone

Obtaining bones

 * Attacking a lion stone can yield bones, among other things.
 * In Adventure mode, on the first island, there are two bones in a crate on the beach, just southwest of your starting location.
 * In Adventure mode, on the fourth island, digging on the Hill of Death (the hilltop covered with dead trees in the northeast part of the island) will unearth bones. There is also a bone in one of the huts in the village.
