Soot Release: Pompeii

Pompeii is a Soot Release jutsu, originally created by Imagetsu Hōzuki, to which he declared a kinjutsu technique due to its destructive power and recoil, though was later used by Tsujikaze member Shōmoui. After placing four corners to designate which areas will be affected, the user then starts storing an immense amount of soot-based chakra, usually over the course of two days and two nights. After that, the user must be in range of the target, chant the jutsu name, and clap their hands. Ash clouds will build up in the sky, and red lightning then falls down on the target, before soon after, pyroclastic flows race down from the highest point near the target, petrifying anything in its path. The ash clouds will soon descend down, further encasing the now petrified victims with more ash.

Trivia

 * The jutsu's name and how it attacks is a reference to the |eruption of Mount Vesuvius, which destroyed Pompeii, and buried it in ash.
