Jutsu ("skills/techniques") are the mystical arts a ninja will utilize in many different situations. To use a skill/technique, a ninja will need to use their chakra, to perform a technique; a ninja will bring out and release the two energies of chakra. By forming hand seals, a ninja is able to bring forth the desired skill/technique. Due to the extensive number of hand seals and different combinations, there are thousands of potential skills/techniques to be discovered.
Ninjutsu (Literally meaning "Ninja Techniques"), is a term referring to almost any technique which allows the user to do something that they otherwise would be incapable of doing, including the usage of weapons. The effects of ninjutsu are real and very greatly in purpose unlike genjutsu that focuses more on illusions. With the simpler ninjutsu serving such tasks as transforming the user or allowing them to evade attacks. These techniques are often second-nature for experienced shinobi, who can use them at will. More complex ninjutsu manipulate one's surroundings or utilize the elements, respectively serving such tasks as healing others or manipulating nature transformations. Ninjutsu most of the time, relies heavy on chakra and hand seals to be effective. A ninja’s hands are put in sequential position that mold and manipulates chakra in the necessary manner to perform a technique. This is not always needed, however, and some techniques become second nature to experienced ninja, after which they can perform them at will.
Genjutsu (Literally meaning "Illusionary Techniques") are techniques that are employed in the same fashion as ninjutsu, requiring chakra and hand seals. However, the primary difference between the two is that the effects of genjutsu are illusory; instead of attacking the victim's body, like taijutsu or ninjutsu, genjutsu techniques manipulate the flow of chakra in the victim's brain, thus causing a disruption in their senses. Genjutsu frequently used to create false images or to cause pain from trauma (because the Ninja under the Genjutsu is made to believe there is in pain); however, there are plenty of other uses depending on the situation. They are not used as often as ninjutsu because they don't physically harm the opponent. Genjutsu can also be used to manipulate others, similar to brainwashing by feeding the victim illusive suggestion. Genjutsu can also be used for other supplementary purposes such as interrogating an individual by breaking their will. A Genjutsu is created when a ninja controls the chakra flow of the opponent's cerebral nervous system, by affecting their five senses. Those with special abilities like the Uchiha clan's Sharingan (which can cast generic genjutsu or with high intelligence have an easier time executing and countering genjutsu.) Those under the influence of genjutsu will either appear to be unconscious or continue to move around under the pretense of the genjutsu. The latter is very effective in battle as a genjutsu user can make them appear to be somewhere else and attack the victim from behind or change the environment to make the victim see a flat plain where there is a steep cliff. Genjutsu attacks usually require a lot of skill and if performed incorrectly will not work. Genjutsu affects activity throughout the pros encephalon structure of the brain, humans, dogs and other species of mammal are therefore all affected by the exception to this is insects; they lack such a structure to their brains, and so do not even notice it: Which makes them immune to genjutsu. There are cases with more complex genjutsu ones that still employ illusions but have elemental chakra natures associated with them.
