Alright, I'm sorry for my late response, I'll be more active for the next 3 weeks or so

"Well if you were skilled already you wouldn't be here now would you. Now then we'll begin. We'll be starting with the discussion of genjutsu breaking. Breaking a genjutsu begins first with recognizing you have been trapped within an illusion. It's very difficult for you to deal with the illusion if you don't have awareness of the fact. In order for you to determine you're in a genjutsu you need to be perceptive and very conscious of your reality from your opponent's fiction. Noticing nuances in the terrain, realizing that a certian occurrence is impossible or unlikely. These are how ordinary and even advanced level shinobi need to figure out that they are trapped.
Some special abilities like dojutsu and sensory abilities help facilitate the knowledge that you may be under the spell of a genjutsu. Since Genjutsu hits and manipulates your natural flow of chakra a very easy way to confirm your entrapment in a genjutsu is to notice your flow of chakra is disrupted. Dojutsu users like Sharingan, Byakugan, and Rinnegan, who have the ability to see basic chakra flow (the Byakugan can see more so) of not only others but themselves can see their chakra flow as normal or disruptive. Chakra sensors can notice their own chakra with their sense and determine their flow is disrupted as well. If you notice your flow is irregular then you know you can safely attest to being trapped in a genjutsu and proceed onward. However these facilitating abilities have a few key flaws. For dojutsu your ability to 'see your own chakra flow' is hindered to a degree based on the strength of your eyes. For example:
Sharingan users becomes stronger in their visual prowess as their dojutsu matures (1 tome, 2 tome, 3 tome, Mangekyou, Eternal). Their ability to see their chakra through a genjutsu also gets stronger. Meaning a high enough level of genjutsu can prevent you from using your eyes to see a disruptive flow. A 3tome Sharingan user cannot use their dojutsu to see irregular flow of chakra within themselves if they are under an A-ranked genjutsu. This is because they can only use their dojutsu for B-ranked level genjutsu.
For Byakugan users the same rule applies however there is only one level of Byakugan. Their cut off is at A-rank as well I believe.
Chakra sensors, however, do not have this burden. Nevertheless, regardless of the facilitating ability this does not absolve the trapped person from being required to realize or suspect (at the very least) they are under a genjutsu. If a genjutsu is subtle enough to otherwise make you feel as though nothing is wrong, you will have no need or no reason to check yourself to see if you're in a genjutsu. As your senses are primarily used against your opponent or to observe the field around you, you're not keeping tabs on your own chakra. Keep in mind that no matter what you need a valid reason to suspect you're in a genjutsu before breaking it.
Do you have any questions before I proceed onto the methods of breaking genjutsu?"
