Poison Moth Genjutsu

Ouroboros passively exerts a poison thin and tiny enough to be taken in the air, two meters out from his body in all directions. His target when inhaling the poison start to see the things that Ouroboros chooses, like caves, moths, or allies of the target trying to kill the target. His target ultimately rendered helpless by the poison, lest they have a sufficient countermeasure in place, or prepared to enter motion, then they are left entirely at his mercy.
