Techniques were like weapons themselves. They allowed Martial Artists to achieve things that they would ordinarily not be able to. They allowed for greater prowess in combat. Lower-grade techniques had a marginal effect whereas higher-grade techniques could change the tide of battle.
Usually, the one with more of these weapons, and better-quality weapons won. They would usually overwhelm with a quantity or a quality advantage.
However, there was a variable that was often left unseen.
Mastery of these weapons. Mastery of these techniques.
Someone who had higher mastery of a technique would defeat someone with a lower mastery. Mastery was an important variable that had significant impact on the outcome of a clash.
Yet, there was a reason people moved on to another technique after mastering one to a satisfactory level. Learning new techniques was easier than increasing an already high mastery.
