Reijutsu: Will o' Wisps

he user is centered around Will o' the Wisps Made from Reiton chakra. The hovering orbs that appear upon the release of the jutsu are all incorporeal. They cannot become substantial or interact with any physical matter that isn't Chakra-based. This makes them completely useless as a defensive technique, as they cannot protect the user from any incoming attacks. However, when they glide through any material, living or not, they leave a pth of withered, cold desiccation in their wake. These routes are drained of their structural integrity through rapid decay. In living creatures it seems as though the flesh has been wracked by a degenerative disease, although it doesn't spread. These attacks can slaughter lesser enemies with one glide through a major organ - the heart, brain, spine, kidneys, and stomach are all common targets. Powerful enemies, such as S rank, Kage ninja or particularly skilled Shinobi have stronger, more resilient organs, and might require more than one intersecting pass before total decay occurs. The orbs are controlled by the user's mental will. They are in no way self-sufficient. Should The user be knocked unconscious or rendered unable to see, the orbs are affected, as well.
