Spirit Stones

Spirit Beasts have inside of them Spirit Stones and can be harvested after the Spirit Beast dies.

High quality Spirit Stones are able to increase the powers of Ring Spirits while ordinary Spirit Beasts only yielded tiny grains of Spirit Stones when they are killed and were too tiny to be set onto Spirit Rings. In general, the higher grade of the Spirit Beast the larger the Spirit Stone

Many people hunt the higher grade Spirit Beasts to gain Spirit Stones that they could set in their Spirit Rings or sell for profit.
