I wish to learn Suiton because it is one of my favourite elements in Naruto and this RP, and it has the most applications of any of the basic 5 that I've seen. Having used Suiton in a couple of mock spars, I enjoyed the variety of uses I had when using it, and I came up with some combo's that I did not know would be achievable. Suiton's weakness is Doton, Earth Release, because Suiton's method of attack is mainly streams or even waves of water, something Doton defends against easily. Suiton is strong against Katon, Fire Release, because Fire is created by the combination of heat, fuel and oxygen. Water is naturally a cold liquid, and that eliminates the heat fire needs to sustain itself. While water has oxygen, the oxygen is so tightly bound to hydrogen that the oxygen cannot react to anything else. Thus, the oxygen is taken away from the fire as a result. Five users of Suiton include Momochi Zabuza, Hoshigaki Kisame, Hatake Kakashi, Hozuki Suigetsu, and of course Senju Tobirama. Suiton is part of, but not limited to, two Kekkei Genkai: Mokuton - Wood Release and Hyoton - Ice Release.
