In chapter's explanation is way better than this short info.
Power System (Ranked by Strength)
1] Sealed Artifacts
Sealed Artifacts are created by sealing unholy creatures within objects.
They corrupt the user in exchange for power.
These beings are usually dormant and can only awaken after forming a bond with the user. Once awakened, they grant abilities in exchange for Will.
Their true goal is to erode the user's Will, gradually weakening their willpower until they can corrupt the user completely, take over their body as a vessel, and gain freedom in a limited form.
Despite their extreme danger, Sealed Artifacts are the highest granters of power in the world.

2] Bloodline Inheritance
This power exists only among descendants of kings.
It is the second strongest power.
Bloodline power does not require training and naturally grows along with the user. However, it is looked down upon by strong and prideful warriors because it has a hard limit—the user can never surpass the ancestor who passed down the bloodline.

3] True Magic
True Magic is the greatest strength that can be obtained by any being.
It ranks third in raw power but is considered the greatest because anyone can acquire it through training, and it has no limit to growth.
True Magic is elemental, formed by the fusion of elemental affinity, aura, and mana.
It is dependent on mana and aura, and therefore indirectly dependent on classes and races, which grant mana and aura.

4] Classes and Races
Classes and races are the fundamental power system wielded by all beings.
They increase mana and aura.
They form the foundation upon which the world operates.
This system is the most stable and secure, granting innate power and skills that are activated using mana and aura.
