Inferno (Element), by Kagi, Flash, and/or Ryu, is currently under construction. As such, some sections may be incomplete.
Inferno is an advanced element of Fire. Inferno is widely considered the "successor" and "pure" advancement of Fire. This is due to the fact that it only requires a high-level of Fire mastery, a talent for the element, and the drive to fuel this element.
In terms of raw power, Inferno is leagues above the Fire element, to the point where even a basic Inferno attack can overwhelm a Fire Blast, Overheat, and even cancel out Blast Burn. A user of this element must be very in-touch with their emotions and equally driven, as it is these elements and this drive that acts as the accelerants for the flames. The result of these accelerants is immediately noticeable; the flames become intense and concentrated like the flames of a jet, in addition to becoming pure white flames. These flames are far harder than those of basic Fire, with far greater speed, force, and concentration, making the attacks seem actually solid. Inferno is capable of releasing an incredible amount of heat, to the point that Water techniques are outright evaporated against Inferno; in defense this can only weaken Inferno, while in defense Inferno can actually block Water attacks. Even Earth has trouble handling it, the raw incincdiary power breaking down and melting the materials over time. Nature and Ice have likewise gone from having a weakness to being completely useless against the sheer power of the Inferno element.
However, Inferno is a double-edged sword, just like its original form. Inferno carries Fire's overall lack of defensive moves, and energy inefficiency. However, this weakness is much more noticeable in the Inferno element, to the point that one without master-level control and a reasonably high level of stamina, the Inferno element would only be capable of being used in short bursts. Otherwise, the user would be left utterly fatigued and incapable of continuing to fight. The Inferno element's intensity and power also makes it much harder to control. This makes it overall far less flexible and much more direct.
