Spirit Rings: Spirit Rings are the souls released by Spirit Beasts following their death, sacrifice, or contract with humans. The Spirit Ring can only be absorbed by the person who delivers the final blow and kills it and should be at a Rank (Rank 10, 20, 30, etc.) to be able to absorb it.

Spirit Rings are usually divided into categories based on their age.

White : 10 Year Spirit Ring

Yellow : 100 Year Spirit Ring

Purple : 1,000 Year Spirit Ring

Black : 10,000 Year Spirit Ring

Red : 100,000 Year Spirit Ring

Unique Colour : 500,000+ Year Spirit Ring

God ring : 1,000,000

There can be variations to the norm in special circumstances.

Spirit Bones: 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 price. 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:

External Bone

Chest Bone

Skull Bone

Left Arm Bone

Right Arm Bone

Left Leg Bone

Right Leg Bone

A 100,000-Year-old Spirit Bone is worth the most no matter what part of the body it is attached to. A Spirit Bone cannot be removed from a person unless they are killed or amputated.

Twin Spirits: During the Spirit Awakening Ceremony, those who have two Spirits Essences are known as having Twin Spirits. People with Twin Spirits usually have Innate Full Spirit Power.
