Northern Shaolin #10 Martial Methods contains a great number of new techniques. This form is sometimes considered to be the form where all the extra movements ended up. It has a wide variety of techniques and many of these do not fit the feeling of the other forms.
Martial Methods is also a pattern breaker. In the other forms, certain patterns are created and then they are modified, or elaborated in other forms. Martial Methods seems to reverse, or counter, some of these patterns and thus breaks up the pattern of the style itself. This helps to make the Northern Shaolin boxer more unpredictable and unorthodox. If a person picked five favorite techniques that were from this form and not in any of the others and focused on those in fighting an opponent could very well not think they were fighting a Northern Shaolin boxer.
This is one of the great things about Northern Shaolin. These forms constitute an encyclopedia of martial techniques from which one can draw their favorites. They are exposed to a wide variety and develop a sense for what is possible and can focus on those techniques that are most suited to them.
One of the great things about this form is that even though it may be the last of the Ten Core forms you learn it is still packed with entirely new moves. That makes it fun to learn. It also expands your horizons with so many new techniques and combinations.
