Rankings
Humanity created a ranking for the 999 strongest skills and artifacts. This ranking puts the strongest as solo numbering from 1-9. The slightly less powerful are given double numbering from 10-99. The less powerful ranking are given triple numbering from 100-999. Other skills weaker than this were not ranked.
Skill and artifacts that are more powerful than the current solo numbering but have not yet been found are called zero numbering.
