Combustion Release: Chakra Disc

The user will gather Combustion Release chakra into their hand(s) and apply shape transformation to make the combustion chakra into a high speed rotation disc, and throw it at the target. The disc can travel at tremendous speeds and is able to easily sever body parts or bisect the target if it hits. The disk can be controlled by the creator to change direction. It can also be created in pairs, and is able to lock onto the chakra signature of a target. As long as the original user maintains their concentration, the Chakra Disk will continue to follow the victim. Once concentration lapses, the attack can wind up anywhere. Since the Disc is made of combustion chakra it would leave a trail of flames after it.
