1. Rain at will - similar to the hiding in mist tech, the user can always detect the enemy through the rain drops. I would use this to detect the enemy while they are in my mist to have a combined eerie effect and to also keep watch on my blind target. Also if I'm in the mist casted by someone else , I could use this to find them and track their movements.
2. Water wave- man tbh I always liked this jutsu since o saw tobirama use it. It forms a vortex without a source and then tons(not really) of water plummits down on , crushing everything and everyone. I also like that this jutsu spans out to long range and is low on chakra but I wish that it was S ranked then it would be nearly unstoppable.
3.powerful blast- i like this jutsu since once directed , it acts on its own so while its attacking I can set up another jutsu. I can also form a dragon from it which is able to swallow the enemy and drown them inside of it.
4.water prison- I like this jutsu since clones can perform it and it has good defensive qualities. But that defense can easily backfire with just a b rank lightning jutsu lol. I dislike the fact that in order for me to trap them, I have to keep one hand inside. With one hand inside how am i gonna weave jutsu? Hmmm? HMMPHM?
5. man **** this jutsu tbh. Its straight but I'm not all into the substitution stuff. Sub's are for puzzies. But yeah its cool how when I get struck I can turn my body into water, but thats it. I can't even attack while in the water form. That's gay.
