This mod allows you to use Knockback, Looting, Impaling, and all other sword enchantment types on a mace while also mixing mutually exclusive mace enchantments.
This mod adds Withered Bones, Withered Bone Meal, Withered Bone Blocks, and a Potion of Decay! Withered mobs no longer drop regular Bones and only drop Withered Bones (This can be disabled in the config).
