Skill

A Skill is an ability that can be learned or obtained, and used with the appropriate Resource.

It is thought that Skills are a type of leftover World Magic. Those who use Skills are usually referred to as Skill Users. All Adventurers are required to be or have the capacity to become Skill Users.

In order to use a Skill, one must also have the required Stat level or higher. In general, the higher one's Stat level is, the more effective their Skills become.

This not only happens because the Skill User becomes more adept at executing the Skill, but also because the body's Resource composition slowly adapts itself to become more suited for the usage of that particular Skill.

As a result, Hybrid classes that make use of multiple Skill Types are not widely used and unpopular in the Meta.
