hmm kai is a useful tech but there are other ways to break genjutsu(pain and all) so basically it is disadvantageous as if you are in a battle,kai counts as a move so it is better to stab yourself or let a clone or an ally inject chakra into you.Als as i am a sharingan wielder i do not require kai,my sharingan can do what kai can do in an instant.XD
The genjutsu i.e kori shinchuu fixes an exact image of the environment around,so if i change the terrain by say earth style fortune of wheel,he wont know shit about the terrain which i can use for a massive advantage.
In another scenario i can use the fixed image of the surroundings ,so if he is underground and i use it on him while he is in the ground i think he will lose his oxygen supply,thus suffocating and dying due to lack of oxygen as he will be simply roaming around in the ground.(if sensei you think i cannot use the tech on an opponent who is underground,then this scenario is voidedxd)
In another scenario if the opponent is charging towards me i can simply place him in the genjutsu,and he will run straight till he realises,but till then i guess i will have gained the time for an attack.
No no, it is amazing. Exelent use of the genjutsu in a battle circumstance. But remember that you have to cast the jutsu short range from your opponent...
Genjutsu: Jinmon (Illusion Technique: Interrogation)
Rank: C
Type:Supplementary
Range:Short
Chakra Cost:15
Damage Points:30
Description: A illusion used to force the enemy to give out info by torturing them in there minds.
This is basically a way to torture someone's mind so much that he/she will tell you anything to make you stop. This is great to know secrets, in a hostage situation, after a war, but there are other uses to this technique, in battle situation.
If you can get closer to the opponent, enough to touch his/her head, you can subdue him due to mental pain. This jutsu relies on your power, and your opponent's power, so the consequences can be death (Nah, just putting your opponent to sleep due to excrutiating pain, since you're much stronger than your opponent) or none at all (since your opponent's much stronger than you) but even if the opponent is one, or two ranks higher than you, the pain and exaustion, even if it's not deep nor long lasting, is enough to make them stop their attack, or handseals. For example, if your opponent has you held by the neck, and is choking you, if you manage to grab his head, you can force him to release you, and, still stun by the genjutsu, will open a window on his defence.
Anything you'd like to add?
