Will do, and thanks for the details.
Listening to senseis word, I start to perform the "Hidding in Mist Jutsu".
I begin gathering chakra in my mouth. I continue gathering chakra before I start changing my raw chakra into Suiton chakra, and once my Suiton chakra is moulded properly, I release it through my mouth in the form of a thick mist that covers the battle field by performing the Suiton jutsu (Kirigakure No Jutsu) - Hidding in Mist Jutsu. After finishing it, I again gathering chakra in my body once again. I then begin releasing the chakra into the mist that I previously created whilst using nature manipulation and shape manipulation to reflect the light so that it blinds everything caught within the mist. Doing so, the opponent is caught in the blinding light leaving him without the ability to see well due to the strong light.
So for the speed, If taken separately, this jutsu is fast. It doesn't need any handseals and you only need to release your chakra into the mist. The shape and nature manipulation happen quite fast too. If taken as two, I think it would take some time, since you firstly need to perform the "Hiding in mist Jutsu", which takes time on it's own and counts as two jutsus to perform.
As for advantages and disadvantages. Firstly, it is a good deceiving jutsu. It can be used escape from the battle while you blind the opponent, to perform another attack while he is blinded or to set up some trick. Also it doesn't require a lot of chakra, but if u keep it active it will take -3 chakra per turn, which is a disadvantage. The biggest disadvantage is that you needed Hiding in the Mist Jutsu to be active, so it can't work as a standalone jutsu. Also doesn't work on long range.
I gather chakra throughout my body before turning my raw chakra into Suiton chakra. I then clap my hands together and release my Suiton chakra from all around my body while manipulating my chakra and using nature transformation. At the same time I use shape manipulation to form a spinning vortex of water around me. I then manipulate my chakra to cause the vortex of water to cascade into a wave that moves quickly towards a training dummy found nearby, completely destroying it.
I think this jutsu is fast. Firstly, the hands clap happens very fast, and in the description is says that the user claps his hands and a vortex is formed immediately after that. What I think might take some times is the process of the formation of the vortex, but still, I think it falls under the fast category.
Hmm, so for the advantages and disadvantages : It doesn't require a water source, which is a great advantage. It can be used on the offensive nad defensive too. It can go up to long range and It can go up to B rank, which is pretty powerful and can cause some real damage. No handseals, only the clapping, which is pretty fast. The only disadvantages I can think is the amount of chakra it requires, and it's elemental weakness, when opposed to earth.
