Acrophobia Technique

Only usable while the victim is in a high place, this technique causes them to instantly suffer from the symptoms of acrophobia the first time they look down or have the feeling they are about to fall or might fall from a decent height such as off a high cliff or branch. Whether or not they stop looking down or move from the position of potentially falling, the symptoms stay for several seconds before disappearing however, it can be longer or shorter depending on the individual's personality however, it typically stays with the victim, making them experience it again the next time they are in such a position though not as severe. Each time they experience it, the closer they grow to actually having acrophobia so even if the Genjutsu is discovered and stopped, a victim who has suffered from acrophobia effects one too many times will have the phobia for real, making them unreliable in high places.
