(Katon: Fuuton Ken Katon Bakufuu no Jutsu) Fire Release: Wind and Fire Blast Technique
Advantage: Not any regular water jutsu can counter it, it uses a wind with it so it very strong to counter. Covers a wife radius and very hard to evade or counter in time before impact. Doesn't require any hand seals to perform so it can be done quickly.
Disadvantage: By adding both jutsu together it takes more time to complete and uses more chakara. The flames becomes larger, and you won't be able to control it and because of the long range if not careful it can injure allies.
(Katon: Gōka Mekkyaku) - Fire release: Great Fire Majestic Annihilation
Advantage: covers a wide radius so it will need a big/storng enough water jutsu to counter. Doesn't need a lot of hand seals to use. Reaches a great distance all the way to long range, is big enough to cover a big horizontal and vertical front.
Disadvantage: because of the size, you won't see anything in front of you. Needs enough chakara to perform
(Katon: Gōka Messhitsu) - Fire Release: Great Fire Destruction
