Fire Element: Great Fireball Technique

Fire Style: Great Fireball Technique - a ninjutsu created by the Uchiha clan and became one of its signature techniques. The user converts chakra in the body into fire and expels it from the mouth in the form of a giant sphere, which retains its shape (not always) until it hits the target. Upon impact, the fireball leaves a crater in the ground and vaporizes everything within the blast radius, while dealing extensive burns to living targets. The power of the technique directly depends on the chakra invested. For the Uchiha clan, this is a traditional coming-of-age test - only one who masters the technique is recognized as an adult.
