Fire Release: Ash Pile Burning

The user spews a stream of chakra-altered gun-powder ash from their mouth, which surrounds the region. As the gunpowder is composed entirely of ash, it stays in the air around the victim like a cloud. After surrounding the enemy with the ash, the user can ignite it with a flint placed on their teeth beforehand to create a spark, resulting in a violent explosion, burning the enemy. However, this technique requires keen senses to read the air currents, the insight to read the movements of the enemy, the tactical experience to not also enfold one's allies in the flames, and careful attention for the timing of the ignition.
