A genjutsu that causes the opponent to think and move half as fast as he/she would normally. This is done by making time move twice as slow within the opponents nervous system by infiltrating it like any other Genjutsu.
Heavily weakens most opponents.
This Genjutsu creates a bubble of a 5 yard radius around the user, and focusses on only one target inside said radius. The Genjutsu only remains effective inside the radius.
