Name: Worst Nightmare (最強の恐れが現実になる (ワーストナイトメア) )

Type: Conjuration

Description: I emanate a signal of sorts in the shape of a sphere. Anyone engulfed within the signal experiences an illusion of their greatest fear. Any senses that can be involved will be involved. For example, if a victim's greatest fear is a snake, then they will likely experience an illusion where snakes are slithering all over them while hissing, so visual, auditory, and tactile senses will be affeted at the very least. If their greatest fear is a memory, as another example, their visual and auditory senses will almost certainly be affected, and any other senses that could be involved will be involved (to make the experience that much more dreadful).

Limitations:
 * I must keep my eyes closed throughout the technique.
 * Anyone within the radius will be involved regardless of my desire.
 * I may not use Nen for any other purpose while the technique is active.
 * The radius of the sphere increases at a speed of, at most, 24 km/h, or $$6\frac{2}{3}$$ m/s. The minimum speed is no speed (0 km/h).
 * The larger the sphere, the more aura I need to expend, but the effect remains the same throughout.
 * Similarly, the longer the illusion, the more aura I expend.
