What about your earth jutsu?
Katon: Sono Gai, - ( Fire Release: The devils Scyth)
Alright, begin by performing the tiger handseal, while gathering your fire chakra. Once gathered, I want you to channel this chakra into both your palms. By using shape manipulation, I want you to then manipulate the chakra to take shape as a large demonic scythe. Make sure that the scythe's handle is roughly the same size as you, while the actual blade is twice your height. The scythe should have enough cutting potential to cut cleanly through, several trees in a row.
Now its your turn. Cut those tree's over there. *Points*
Katon: Sono IjinKiga - ( Fire Release: The devils hunger)
Alright begin by performing the snake-tiger handseals. Once performed you need to channel your fire chakra into each hand. A blazing ball of fire should be created from each hand. Once the ball is created , manipulate it creating a large demonic head with powerful snapping jaws. Run up to my clone and slam one demonic head on each side of their body, trapping them in a blazing orb of fire that keeps them trapped as long as you hold the snake handsesal.
*Creates a clone*
Katon -Hinotama Kara Makai- Fire Release - Fireballs from hell
Begin by channeling your your fire chakra into a cigarette. Toss the lite cigarette into the air. While its in the air, increase the amount of chakra that was in the cigarette causing the lite end to create several sparks that shoot out from the lite end. By using shape manipulation shape the sparks into fireballs that shoot up into the sky. Once in the sky, direct the fireballs to shoot down onto a area below.
*Gives you a cigarette*
