ok. now that is typically used to generate the stormclouods for kirin, but I beleive stormclouds can be generated by any heat source as long as the fire can reach the clouds. The jutsu range for this is listed as short to mid, which is WRONG. It should be listed as short to long because it has to reach all the way to the clouds. Amirite?
moving on. the next one is nice but tricky.
(Katon: Haisekishou) - Fire Style: Burning Ash Accumulation
Rank: A
Type: Attack
Range: Short-Mid
Chakra cost: 30
Damage Points: 60 (+10 damage if the opponet escapes before explotion do not calculate the 60 if he/she escape just the 10)
Description: User utilizing his fire chakra, inhales and spits out a cloud of ash which begins to envelope his opponent and explodes when the user clicks his teeth. However, this jutsu will cause major damage to his skin and lungs if the user doesn't escape before it explodes.
I say this one is tricky because the ash moves with the wind currents. if you are downwind, then the ash will blow back on you, and you don't want that.
Start by concentrating you chakra in your lungs. As you blow out, form the chakra into small bits of ash. use your composition and shape manipulation. This ash will be loaded with volitile katon chakra that should be ready to erupt when you click your teeth.
If you can keep the target in the ash, they will eventually breath it in, and that will cause major damage when it explodes
this katon is unlike other katon because this is not fire or a fireball. his technique focuses on explosions. try it out.
