Kangiten

The user of Kangiten looks at something and creates a black tinted orb of "death." In this orb, certain jutsus can be nullified and effectively killed. Organic materials, such as grass, yellow and die if they are within the orb. Multiple orbs can be created and their size depends on the amount of chakra put into it. If these yin-chakra energy balls come in contact with a human, then they're weakened severely and have their chakra drained. The orbs are also stationary and cannot be moved around or shaped into any other shape.
