I've never used any of the D-ranks except Hidden Mist, that's three right there. I can tell you that for sure.
(Suiton: Suiben) - Water Release: Water whip
Rank: C
Type: Offensive, supplementary
Range: Short - Mid
Chakra cost: 15
Damage points: 30
Description: After the user performs a series of 3 hand seals Rat → Dog → Ox, the user creates a whip of water that can be used to strike the opponent with a lashing action or wrap around the target to bind them. This technique can also have lightning techniques channeled through when they have bound their victim with the water whip.
A pretty basic technique, you do three hand seals and create a water whip. Some of the techniques are really simply like this one so I won't explain much or demand of you to say much either. As long as you understand what it does. This technique bluntly shapes water into a long whip then ummm... whips the opponent. You can use it to serve any purpose that a normal whip can.
(Suiton: Mizuame Nababara) - Water Style: Starch Syrup Capture Field
Rank: C
Range: Short/Long
Chakra Cost: 15
Damage Points: N/A
Description: The user After performing the required hand seals Ram → Tiger spits out high-viscosity, chakra infused water, aimed at a surface of wide scope. This is a stream of sticky liquid which can be used to form an adhesive trap that can inhibit a person's mobility. One can effectively reduce their enemy's area of activity with this technique, and has the effect of being able to take complete control over the battlefield. The normal scope of this technique is normally just a few metres, but if prepared, it is also possible to make an entire pond of starch syrup. Being caught in the technique can be avoided by channelling chakra to one's feet allowing one to walk upon it uninhibited, beforehand.
This technique is a little more complicated even though it requires less hand seals, only two. After transforming your chakra into water inside your body, you need to take the technique to the next step. You need to infuse your chakra into the water and increase the viscosity by bring the water molecules closer together and preventing them from moving as freely as they normally would. You then just spray the viscous water out of your mouth into the ground or any surface you want. The water is infused with your chakra so your opponent cannot use it as a source for their water techs but they can counter it by channeling their own chakra to their feet to allow them to walk on top of the water before they sink into it.
