Indar

Indar (凍傷) is a technique that originates from Angra Mainyu's left Mangekyō Sharingan. Similar to Amaterasu, it manifests in the form of black flames, however, it boasts a small collection of differences.

First and foremost, the flames do not emit heat, rather, they are a supernatural fire that instead threatens to freeze all organic life (similar to various Ice Release techniques), and virtually anything that emits heat. The rate of which these flames freeze is determined by the amount of heat the target emits; when used on a tree, hoarfrost would develop in a couple of minutes if uninterrupted, while when used on a technique such as Amaterasu renown for the hellish sun-akin temperature it offsets, would quell the flames variably under a minute.

The flames though have no effect on inorganic life, such as kunai, and will simply linger on its surface. In accordance with this, Angra Mainyu shrouds his Gen'ei in the flames, which due to the shadowy apparitions themselves lacking body heat, and generally being the byproducts of his subconsciousness are immune to its freezing effect, while being capable of making practical usage of it. Gen'ei shrouded in these flames are somewhat-easy to distinguish from the regular rabble, offset by the blue tinge in the flickering shadows their bodies produce.

Indar ignites in various forms, be it directly in Angra Mainyu's vision, where it is considered unavoidable as with in the case of Amaterasu (while not being technically correct, given the small quantity of methods capable of evading being directly hit), or simply in the form of a sphere augmented to explode, a shower all lifeforms beneath in a downpour of these heat-opposing flames.
