Not to mention, the Water Divination was introduced incredibly early in the HxH when Togashi himself wasn't even sure what he should make out of and do with Nen, it really shouldn't be used as any ability's basis.

There is a reason why Togashi expresses exactly 0 attempts in solving the paradox of "what would happen if Nen users were to fight in water" even during the scenes where the combatants were literally fighting underwater, while the surrounding water doesn't seem to give a shit about their hatsu.

So tbh, a power based off Water Divination with everything considered, really isn't a good idea.
