Swamp Gas

Chakra is kneaded within the body and then changed into special chemical substances which is then ejected through the mouth. When this substance comes in contact with the air outside the body, it instantly changes and is transformed into a highly-corrosive and poisonus gasious mist. It adopts the form of a purple, smoke-like mist that will gradually spread, corroding away at all organic matter caught within its shroud. It may also corrode inorganic matter, such as buildings and tools, however its rate at doing so is halved. Upon inhalation, the victim's fate is practically sealed, the mist quickly spreading within their body and corroding their vital organs, ending their life within several seconds.
