*I stand here with my 2 tomoe active, waiting for ~Crow~ sensei*
ok inorder to get the 3T sharingan , you need to go through 3 special training sessions like the following >_>
First training session: The Sensei will make sure that the student can locate him into any environment (close range) and somewhat predict his attacks which will be as fast as possible now. Training ends when the student is able to do this without mistakes.
Second training session: Genjutsu training up to B rank -no custom genjutsu-. The student must gain the ability to see through all genjutsu attacks. When this is succeeded, the sensei will make a very very fast attack to the user, strong enough to knock him/her down. If the student does get knocked down the First training sessions steps must be repeated here. If he/she doesn't, the sensei can proceed to the last training sessions.
Third training session: This will be proper battle between the sensei and the student, with Sharingans activated for both. The level of the battle must be high with the sensei making sure that the student uses everything he has known of so far. Finally, sensei can assign to his student a mission asking him to use specificaly Sharingan techniques in a battle or something similar to this.
