Fire Release: Ash Pile Burning

The user spews a stream of Chakra-altered gun-powdered ash from its mouth, which surrounds the region. The gunpowder itself is hot enough to cause third-degree burns on the victim, and because it's composed entirely of ash, it stays in the air around the victim like a cloud. For further damaging the enemy, the user can ignite the ash with a flint placed on their teeth beforehand to create a spark, resulting in a violent explosion. 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.
