There are five types of chakra; Fire, Earth, Lightning, Water and Wind. By identifing your chakra type, you can find what jutsu's will work best for you. Such as, Fire types excell at fire based jutsus but they are weak when it comes to water based jutsus. You can also mix your chakra if you have more than one. But I will only allow these mixtures as Kekai Genkais. There are a couple of different ways you can mix them below:
Water + Wind= Ice
*Earth + Lightning= Metal
Earth + Water= Wood
Fire + Wind= Smoke, Ash
I'm sure you can make many more combinations but these are just to list a few. If you would like to mix your chakra in the future please list it as your Kekai Genkai anyway even if you cant use it. Also, combinations must be aproved by Kage and/or me. If you want a combination it must make sense. You cant have Lighting + Wind= Rock, that combination would not be acceptible. Please be creative, and remember just because one combination makes a certain element doesnt mean that the same combination wont be able to create another element. You can still use say, Earth + Lightning= Rock (horrible example) and it can be perfectly fine.
Any questions, post them here. Also feel free to post different combinations if your bored. ^.^ Maybe someone will use them!
Remember you can use any element, even if its not a main element. You cant use two chakra types to make another chakra type. Like :Lightning + Wind= Fire (big no no! D:<)
