As I experimented with various skills, one truth became evident: the more I trained, the more layers these abilities revealed.
Some skills, like an unchanging melody, maintained their essence no matter how refined my understanding. Others, however, evolved dramatically, revealing unexpected potential as their mastery deepened.
One such skill was Reproduction. The more proficient I became, the more it inspired innovation. At its core, the skill allowed me to "segment and repeat" movements—a function that could also be applied to skill combinations.
Take, for example, a combo I devised called Ground Adhesion Technique, created by combining Unbound Thought and Cling. Two skills merged into one seamless action, with a combined cost of two resource units.
