← Unique Skill
The specific requirements to obtain an Ultimate skill are quite vague. However, it seems that those of very high ability are able to develop them. The majority of Ultimate skill users are quite old (hundreds of years old). The younger Ultimate skill users developed them once becoming a True Demon Lord. An ultimate skill strength is such that it must be defended against with another Ultimate Skill/Ultimate Gift.
A normal human’s body can’t handle the burdens of an ultimate skill’s energy. Under normal circumstances, awakening is impossible. That’s probably why the modified body of an “Otherworlder” is needed. But, at the end of one’s training people will “Evolve”. Their race aside, there certainly is a change. In other words, from a human to a sage.
Ultimate skills are able to be bestowed upon by one's master, but in a much weaker form, an Ultimate Gift.
