Lightning Release: Regicide

By utilizing the properties of chakra flow and the element lightning, members of the Shinja Clan have been shown to dramatically increase their reflexes and overall speed by electrically stimulating the somatic reflex arc; a neural pathway that controls the action reflexes within the body, and the optic nerve to increase visual acuity. Unlike similar techniques, which have been shown to require one to wrap the body in a layer of intense chakra, this technique is completely anonymous and is activated without the usage of handseals. In terms of usage, this technique can allow the user to see with an extreme degree of clarity, though not as defined as a doujutsu, and react with speeds rivaling those of similar anatomical techniques.

In terms of drawbacks, the concentration required to pinpoint the reflex arc and optic nerve is enormous, requiring the user to stand still or remain under cover for exactly two seconds; which, as any shinobi knows, battles are won in seconds. Also, damage inflicted by the Wind Release upon the spinal cord could potentially deactivate the technique.
