Charred BoneEditThe Charred Bone is a common drop from Wither Skeletons, found in the Nether. However, it can also be synthetically created by smelting a regular bone. This type of bone cannot be fed to wolves, nor can it be used to create bonemeal, because of its lack of nutritional value or marrow to assist in the fertilization of soil.
It is used to brew the vanilla Potion of Wither. The hierarchy is similar to that of all other potions: redstone elongates, Pure Tear elongates the elongated potion, glowstone amplifies, Plagued Tear amplified the amplified potion.
