Once more, Elijah listens to the words of his student. His way of explaining wasn't wrong, he just had a hard time of putting it the way he wanted, but Elijah understood what he meant. It seems like he always caught his students off guard.
"Hmm, I see what you mean. Allow me to elaborate. There are two ways to deduce that you are in a Genjutsu. The first one is to simply figure out that it's a Genjutsu. Basically how you explained, you have to analyze the information that you are seeing, hearing etc. and deduce logically why it can be a Genjutsu before breaking it. This is a bit slow, but its the most used method around, however, there's always a chance that you could be wrong.
The second way of doing it, is to notice the fluctuation of your chakra once the Genjutsu has been induced. This can be done with a sensoring ability or Doujutsu, so we won't be going too in detail there. However, one must first notic that you are in a Genjutsu before using your Doujutsu, or sensing ability to see if you are in a Genjutsu."
Elijah then smiled, knowing that they had to move on to the next part now.
"Alright, if you understand that part. We can move on. Next, I want you to tell me everything you can about breaking a Genjutsu? This is after noticing that you are in a Genjutsu."
Elijah then waited once more, eager to hear the answer of his student.
