Spirit Bones are the bones which are left following the death of a Spirit Beast. The chances of a Spirit Beast dropping a Spirit Bones is extremely rare. But the possibility of dropping a Spirit Bone does increase if the Spirit Beast feels huge amount of resentment before getting killed, dies willingly or if the Spirit Beast are grateful for their death.
Spirit Bones can be sold and bought, but at a supremely high prices. Even wars occur to take these bones. There were once two countries that fought for a 20,000 year old Spirit Bone and lots of people died. That is why, the 10,000 year old Spirit Bones are also known as The Treasures of the Bloody River.
Spirit Bones are considered as extremely important, as much as Spirit Rings, as they provide new abilities to the wielder. A person can use 6 Spirit Bones on 6 parts of the body, which cannot be overlapped. According to their importance they are:
Left Arm Bone
Right Arm Bone
Left Leg Bone
Right Leg Bone
A Spirit Bone cannot be removed from a person unless they are killed or amputated.
Human Spirit Bones
Just like spirit beasts, spirit masters also have spirit bones. Compared to spirit beasts, humans take less time to form their spirit bones. It is called True Body Armour on the mainland and Combat Spirit Bone Plating True Body on Sea God Island. After absorbing six spirit rings, the spirit bones take on an embryonic form. The development process is divided into three stages:
First Stage: Activating the Combat Spirit Bone Plating True Body
It begins when a spirit master reaches rank 70 and is ready to absorb a spirit ring. The quality of the 7th spirit ring will determine the quality of the True Body Armour, so the higher, the better. The 7th spirit ring is like a key to a locked door, it activates the Combat Spirit Bone Plating True Body.
Second Stage: Imprinting the Combat Spirit Bone Plating True Body
Third Stage: Awakening the Combat Spirit Bone Plating True Body
External Spirit Bones are extremely rare forms of Spirit Bones which deviates from the normal six Spirit Bone infusion sites. Their value is immeasurable and second only to 100,000 year Spirit Rings. They have the possibility to grow and evolve into higher forms.
Spirit Bone Fusion is a process where the Spirit Bones within the body undergo fusion producing additional abilities. Such abilities are all extremely formidable, their boost to oneself no less than that of two Spirit Masters joining hands to use a Spirit Fusion ability. Moreover, because it’s produced by the Spirit Bones themselves, it’s capable of reaching a seventy percent degree of fusion.
Spirit Bone Fusion abilities rely on the attributes of the spirit bones and still, to a very large degree, luck. The greatest challenge caused by spirit bone fusion abilities is, in order to produce such an ability, a person must first gather a complete set of six spirit bones. Afterwards there’s a one in thousand chance of a spirit bone fusion ability appearing. An exemple is the Divine Angelic Raiment.
