Forcing water through wounds is not an option sadly, simply because of its heart pumping; you can never outcompete the amount and pressure of blood shooting out from the wound with weapon strikes.

But I believe that its weakness to water has to do with actually breaking/cutting into its shell though. But even with that in mind there are still a lot of possible explanations anyway. Maybe some in-game description of its material can help shed more light on it. I don't have MH4U yet and it might take a while.

Man, I missed the theory blog lol. Is it still active?
