Fire Release: Great Fireball Technique (Tsuneyoki)

A technique where chakra kneaded inside the body is converted into fire and expelled from the mouth either as a massive orb of roaring flame or as a continuous flame-thrower. The scope of the attack is altered by controlling the volume of chakra that is mustered. The released flames will engulf their target, and leave a crater in the ground's surface.

The Uchiha clan uses this technique as a "coming of age" rite, and as such, is a common and favoured technique amongst most Uchiha.
