Description: The user starts by performing a sequence of seals, Tiger, Horse, Dog, Dragon, Dog, Horse, Tiger, and begin's channelling a large quantity of Fire Release Chakra into their surroundings. As they do, they apply a change in the shape of this Chakra, causing it to take on the form of superheated Ash, which erupts forth from the ground, and expands outwards from the users position. As the Ash spreads, it engulfs the battlefield, filling available space while potentially destroying nearby existing structures and topographical features, before twisting itself into a horrid structure of ash, the exact shape, or more specifically, architecture of which depends on the user's tastes, before rapidly cooling. As the Ash cools, it creates a thin hardened layer on the outside, but still leaves the interior a writhing mass of burning ash. If left alone, no change occurs, but if the hardened external shell of the structure is disturbed, even slightly, it cracks and crumbles away, causing a violent reaction. The weakened portion immediately bursts open, unleashing the burning ash along with a mass discharge of thermal energy, which blasts anything within a 5m radius of the cracked portion, forcing them back up to 10m away. As it does, the first step of this cycle begins anew, restarting the cycle of this Jutsu, causing the newly expelled ash to expand outwards, like the branches on a tree, before hardening once more. If one is surrounded by this technique, and the external shell is broken, either by themselves, or another, both intentionally or accidentally, they can find themselves effortlessly tossed around by multiple consecutive explosive bursts of thermal energy, thanks to being thrown from one section of the Jutsu's structure to another, to another, each time cracking open the exterior of the Jutsu, causing it to further expand, and engulf them in an ever-growing malicious mass of destruction. Anyone wishing to safely travel across the created structure, user included, one must create and consciously maintain a constant flow of Fire Release Chakra from their feet, which heats and softens the brittle outer shell as they walk over it, before cooling once more, essentially mimicking the initial step of the technique. If this flow of Chakra stops, similarly to one ending their performance of either the "(Ki Nobori no Shugyō) - Tree Climbing Practice" or "(Suimen Hokō no Gyō) - Water Surface Walking Practice" techniques on their respective surfaces, it will immediately cause them to disturb the structure, triggering the explosive combustion portion of the technique. However, in the case of Primary Fire Release specialists, as their own Chakra flow has a natural disposition towards Fire Release, they can safely travel across/ within, and interact with the structure, so long as they don't intentionally disturb it. Thanks to these qualities, the created "Domain" can easily act as a neutral ground of sorts, forcing those present to adhere to the strict requirement of the maintained flow, making the usage of other techniques impossible, lest they trigger a cataclysmic reaction that could easily overwhelm, and consume them.
Note: Can only be used once per battle/ event. If used in the Ninja World (Or Warring States Era equivalent), this technique forces a semi-permanent change upon the Landmark it is performed in, causing the basic topography/ structural layout to change to suit the user's design, as explained within in their performance of this Jutsu.
Note: While the "Domain" itself can persist through NW/ WSE Events, there can be no more than one Domain per user at any given time. If a Domain is created while another exists, the previous domain collapses into ash, and scatters to the winds.
