Genjutsu
Genjutsu represents the character’s ability to manipulate their own chakra or the chakra of others to affect the mind. The use of Genjutsu never conjures anything in the physical realm; it merely uses chakra from the user and often times the enemy to confuse their senses and make them believe that they are experiencing that which is not real. Users of Genjutsu can causes enemies to see copies of themselves which do not really exist, make people believe they are under assault from deadly attacks that do not exist and even make a person believe they are in a location that they are not. The more training a character has in Genjutsu the more powerful their own attacks come, but it also allows them to see through and reduce the effectiveness of enemy Genjutsu attacks as well.
