I begin by building and gather my suiton chakra, releasing it outwards into a medium sized water source that has been magically created for complete convenience. I then perform the 'Tiger' and 'Ox' handseals, and through use of these handseals mould and manipulate my chakra. I then perform the tiger handseal, causing the water that was hurtling towards a tree, again magically for absolute convenience, to explode outwards. The water forcefully and hastily surges in all directions, blasting its surroundings and leaving the area drenched.
Couple questions.
1. I'm guessing you don't have to be in contact with said water source, and the water source applicable can be anywhere within Long range right?
2. Does this water source have to be either devoid of chakra or containing your own chakra? Or can you use it on jutsu that contain your opponents chakra provided that this technique is of an equal or higher rank?
3.Is this a literal explosion, or is it just water forcefully surging outwards?
4. Does the water have to be moving, can it be stationary? Eg can you detonate a pool despite the fact that it hasn't necessarily "just now come in contact with an object or opponent" since it's either been in contact with it/them for a while?
