Let's continue with the example of the Divine Mountain Empire's spear technique.
Suppose Sterl masters this move. The three accompanying skills wouldn't matter much. He'd be able to use the spear to enhance his output and deflect enemy attacks purely with technique in close combat.
In fact, even if he doesn't use a spear, but other long weapons or even fights bare-handed, Sterl's combat skills would still see a significant improvement.
To illustrate, Sterl's previous fighting style relied heavily on using powerful skills, much like someone carrying a rocket launcher, launching a rocket with every attack, devoid of any finesse. Once he masters the ultimate technique, he can engage in close-quarters combat with skill and precision, countering moves effectively.
