Good!
Now the following, listen carefully.
1. A-rank fire vs A-rank wind : Fire takes over the wind and becomes a fire/wind combo
S-rank fire vs A-rank wind : Fire takes over the wind and becomes a fire/wind combo
A-rank water vs A-rank fire : Water puts it out and continues.
S-rank water vs A-rank fire : Same as above.
A-rank water vs S rank fire : Both jutsus cancel each other out and steam is created.
Remember it and try to use it during battles, got any questions then ask me and the other thing is combinations if you ever want to combinate jutsu's then simply look at the following thing beneath.
2. Fire + Earth = The fire heats the earth up, thereby causing it to melt, and turn into the substance known as Magma/Lava.
Fire + Water = Steam, a good way to conceal yourself, the fire heats the water up and thereby turns it into steam. The Steam itself can't be used as an attack, (exception - Han) but it's a great way to confuse your opponent.
Fire + Wind = Stronger fire, a good and often used combo, but it isn't exactly a new element or anything.
Understood?
