Genjutsu: Sharingan

This technique is simply the generic use of genjutsu as employed by Sharingan wielders. By establishing direct eye contact with the intended opponents, the user can lock them within a genjutsu of their choosing in order to achieve various effects. These effects range from inducing instantaneous, but temporary, paralysis or unconsciousness in an opponent to forcefully extracting any valuable information that they possess  or controlling their actions.
