I believe this information will benefit you the most during this training. I mean you get to learn techniques and such, but this information is the best i believe.
In order to break a genjutsu, you must know genjutsu.
lol okay, that was kinda weird.... anyways what i am trying to say is that every genjutsu is breakable. The way it is set up, even customs [barring old genjutsu customs and old sharingan genjutsu customs], every genjutsu is breakable, even the forbidden ones. Now you might ask is how.... well it's all logic based. RL and in Naruto, it really doesn't matter. Most genjutsu use something that is real and make it appear to the person in front of you. Binding, jutsu, whatever, so how do you know?
It's very simple. There are Key words to each genjutsu that makes it known that it is a genjutsu. It's usually very subtle but the hint of falacy exits through these key words. With the combination of key words and the genjutsu technique itself, you will know that it is a genjutsu. I am going to help you identify the key words of each cannon genjutsu, now you might ask, but it's not the real you that are breaking from a genjutsu and your character/bio needs to know that is genjutsu. It's simple, you use your own logic as if you are in the battle. That way you know and will know how the bio/character will know that it's genjutsu. However it could be a double edge sword, because if you deduce it wrong, you will most likely be in a bind during a battle, so the accuracy of your deduction is critical. So in order to teach you this, lets start with the first technique.
( Magen: Kokoni Arazu no Jutsu ) - Demonic Illusion: False Surroundings Technique
Rank: D
Type: Supplementary
Range: Short-Mid
Chakra Cost: 10 (+5 if you use it double)
Damage Points: N/A
Description: The user casts an illusion over an area that allows him to manipulate the way an area looks to fool an opponent. He can only change the way the terrain looks, and not any other feature.
Read how this technique works and tell me what you think of the key words are here. While using the key words, tell me what is impossible it to happen in this situation to make it real.
From now on we will do techniques but the questions will remain the same. If you can identify the key words and tell me whats wrong with the logical part of this jutsu than you know what this jutsu is doing. Thus the boring "perform" this jutsu doesn't have to be done. Questions during these excersize is not a must. However, I like to keep it like a discussion type training so, ask questions when you have it. Even if it you think it's stupid, it's better to ask then not know for sure.
