Scorch Release: Great Fireball Technique

An advanced version of the Fire Release: Great Fireball Technique which utilizes the black flames of Amaterasu and the flame-amplifying abilities of Wind Release.

Usage
The user first forms a small fireball from Amaterasu's black flames. At the same time wind-natured chakra must be kneaded and formed in the user's lungs, which is then blown-upon the black fireball. This exponentially increases it's size to twice that of the signature Uchiha technique. And because of it's greater mass it is able to travel a farther distance than the original version.
