Mohrpheus on page 20 of that chapter (mangapanda) he states that ALL water is his weapon. The on the next page he states that all the heavens is at his command.

That is still water just not water in the imminent area.

And later in chapter 507 when Yammoto releases his bankai Hitsugaya states that all the water in Soul Society is slowly disappearing and therefore his Hyōrinmaru can no-longer be used.

So if he does not need water to use Hyorinmaru then why does he state he does?
