Bone Material

Bone Material is required by several things, such as Bone Arrows, Bone Hooks and Bone Saws.
==How to Acquire==
All animals contain Bone Material. Killing and butchering an animal will result in a quantity of bone material dependent on the type of animal see Creatures for more information.
Do note that animal specific materials such as Moose Antlers, Deer Antlers, Boar Tusks, Bear Teeth, Crab Shells and Wishbones also count as Bone Material, so be careful when crafting with these items in your inventory
