What makes this jutsu special is that it resonates with the chakra that was previously sent into the opponents mind. This is followed up by the simulations that is experienced prior to the messages sent to the brain. The mental damage that is experienced from the hell hounds, the messages that are sent to the brain are now amplified, The opponent now experiencing physical pain during the genjustus, the chakra fluctuating and inflicting internal damage in unison to the events happening during the genjustu. This Genjutsu can also be served as a medium, being used in combination with other genjutsu increasing their rank effectiveness while keeping the original rank cost. As long as the ketsugogan remains active, this justu cannot be broken due to the fact of it resonating with the chakra implanted into the opponents mind, and the opponent will continue to experience physical pain as well from genjutsus.
It's the ultimate genjutsu, but only Amon and I can use it.
