The third... well, as I said before, I'm still not convinced creating a fireball with your chakra is the same as converting your chakra into a fireball. Remember Saskuras chakra-traing at the beginning of the manga. Everyone has all 5 chakra types, mixes them and uses that energy to create something. You learn that at the academy. Converting the nature if your chakra itself from chakra into something else is a totally different matter. But yes, one very likely can learn jutsus that relate to ones affinity more easily.Originally Posted by Yukimura
This would explain Sasukes hardship with the great fireball, Narutos success with rasengan and even Kakashis inability for rasengan/yellow flash (wrong type!). And boosts the third, being able to learn high class element jutsus from elements of not his type.
To your problem with the bunshin training.... yes! Absolutely YES! This would work for Kakashi. Create 2 bunshins, try something out, feel the chakra flow. Cancel the bunshins, learn that A resulted in X and B resulted in Y. Conclude that a little bit of A helps B and if you then try C, you might get the outcome you desire. Create bunshins again and try that out. Naruto is too dumb to grasp logical conclusion like that![]()
