Usually, the transcendent power in bones and fur is the most stable and mild, while the power in the flesh is a bit more active but also the most likely to dissipate, and the blood... is the most violent.
Thousands of years later, the demon beasts would be like this, so the wild beasts from thousands of years before must be even worse.
The blood of wild beasts contains a rich transcendent power, but at the same time, the power within the blood of the wild beasts is the most chaotic and the most difficult to harness, and even has a strong polluting and corrosive property.
To create transcendent items, you need stable transcendent power; blood, which is relatively active, is used in sacrifices and rituals, so for the Elf Clan, the value of transcendent blood is naturally lower.
Of course, that's for the Elf Clan.
From Charlotte's perspective, the situation was quite different.
Pollution?
Corrosion?
