Collaboration Techniques (コンビ術, Konbijutsu), also synchronised or combination techniques, pertains to a branch of techniques which entails powerful techniques that are actually comprised of at least two or more pre-existing techniques. When initiated with the right timing, one will feed into each other to become a technique of greater power than the sum of its parts.
Collaboration techniques are all about teamwork. Although collaboration techniques can be used by Martial Artist who can simply match each other's timing, the best results are seen when collaboration techniques are implemented by users who are mutually like-minded and have a working understanding of each other's drives and character; the more time they spend together, then the more they can potentially become in sync with each other. This techinques can be used by both Saving Fist and Killing Fist users.
