First technique is pretty basic liquefy a portion of my body, manipulate resulting water to surround opponents head until they pass out or die.
Second technique is basic also, it requires the use of the water dragon to knock the opponent into the air before crashing them into the ground with a sword.
Third technique is pretty much like the first, except this covers a longer range and has more uses, instead of just trapping the target's head, their whole body can be trapped instead, restricting their movements.
No questions.
I can think of some fun times when it can be quite useful
