Very good, and yes, Water is indeed quite cool. There have been some shinobi who have shown that it is possible to only use Water and still dominate their opponents. Good explanation too, Water is strong to Fire since it douses the Fire but weak to Earth due to its strong an sturdy structure. Nonetheless, Water can be offensive, defensive as well as supplementary. It also comes forth in different forms, from normal water manipulation, to oil based forms, sticky water and even mist, to name a few. All these will come forth during training.
My training is quite simple, I will ask you to analyze a technique I had explained. In this analysis, you will give me some strengths and weaknesses of Water, how it can be used in battle and anything else that you feel is relevant to the technique, and questions too if you have any. Don't hesitate to ask. Ready to begin?
