The user has to perform a long set of hand seals, and by focusing their chakra and applying shape manipulation they start forming a body of water from thin air, making it a long, spinning column of water that takes form of a snake. Using the users chakra, it goes forth and attacks the opponent with it's jaws, crushing them and then carrying them off by turning into a river that could potentially drown the enemy as well. The range is pretty large so you could perform this from a save distance while also giving a nice water source for other techs just in case.

The user focuses their chakra and applying shape manipulation, makes it into a sphere that traps the enemy within it. Unlike the previous version of this jutsu, this one allows you to move freely without having your hand inside the sphere. However, the user must concentrate their chakra into this at all times in order to keep it going. If the opponent doesn't get out in a turn or two, they'll drown. This also gives a good water source and can lead into good combination with other techs and customs as you mentioned. It's range is also better than it's previous version as well, making it a lot more usable.
Senpai, by any chance did you see the reply I gave you on my custom bio?
