Hell's Comet of Destruction

An extremely powerful and very difficult to learn ninjutsu developed by Kuhaku Mugen. The user creates a black sphere using their hands and then apply their chakra to the arm the user is using to make the sphere, making the entire arm covered in a chakra coloured haze making the sphere resemble a comet hence it's name. The user also needs to add a nature transformation to the sphere to increase it's lethality, which can make the sphere can additional effects on it e.g Lightning Release + Black Sphere = Lightning coarsing over the sphere. The sphere can be thrown at targets though it's greatest power comes from when the user smashes the sphere into the target like the rasengan able to effectively wipe out an entire village from the resulting blast without harming the user.

Requirements

 * The user needs to be able to use both Shape Transformation and Nature Transformation which is extremely difficult to do at the same time and as such few shinobi are able to do it.


 * This technique requires years of training. According to kuhaku, it took him several years to master it, even with the assisstance of clones.


 * The user "requires" extremely good chakra control in order to use it as even ninja with good chakra control won't be able to do it.


 * The user needs a lot of concentration forming the sphere as even being a little bit off will result in lethal repercussions.


 * The user needs to have large chakra reserves due to the techniques power and complexity. As such, it isn't recommended for a ninja with a desent supply of chakra.

Due to this. Most would consider this fairly pointless to learn this technique other than for it's power. Those that have mastered this technique are to kuhaku, a testament to that ninjas power and skill.
