In player terms, a single attribute needed to be at least 35 to meet the basic requirements for a domain.
However, this alone was not enough.
After a single attribute reached 35 or more, the professional himself also needed to have experienced enough "trials."
For example, the series of titles Kael obtained was essentially a summary of his experiences and achievements, which he earned after accomplishing nearly impossible feats in the dungeons.
[King of Monster] represented his past of daringly devouring and utilizing the flesh and blood of the totem.
[Lord's Certificate] represented the crystallization of his outstandingly effective achievements as a Border Lord while expanding his territory.
[Intermediate Totem Power] symbolized his great achievement of assimilating the power of totems that once stood on equal footing with deities and converting it into his own power.
