Shuso-Retsujitsu: Soaring Inferno

Performed only when Retsujitsu contains more Fire Nature chakra than Shuso contains Wind. The blades are clashed together in quick secession, causing the Fire and Wind Nature chakras to mingle. The presence of more Fire Nature chakra causes the formation of a condensed Inferno, compressed into a sphere no bigger than a marble. This sphere can be held or stored for up to a week without any loss of its destructive power, but when it is stored past that point it becomes dangerously unstable and likely to release at any moment. Once released a raging inferno is unleashed upon the surrounding area, up to 100 yards, and a large column of flame blasts into the air. These flames burn hot enough to destroy whatever they touch completely, yet they only affect the surrounding area and will never spread. The displacement of air and upward currents created by this technique is enough to create both an airless space and a thunderstorm, although only one or the other can occur. The ensuing shockwave can level buildings within half a mile. The power of this attack depends on the amount of chakra poured into it, ranging from a distraction to widespread devastation. The drawbacks to this technique are: one of these destructive orbs can be created every five days, the amount of chakra needed to create one is massive, they must be placed at the target either by throwing it into the general area or by other means, if placed by hand the user must vacate the immediate area of roughly 100 yards but remain within 125 yards to be able to detonate it.
