I'm also not an authority on this, these are just my own personal thoughts.
For sake of game balance, I wouldn't advocate that with water reimancy you can easily strip someone of all their water content. In a more practical sense, it takes time for water to move through permeable or porous material. I've even studied / done calculations to determine groundwater flow through clay vs. silt vs. sand... Not going into the mathematics, it can take a decent amount of time for water to travel. And substances like clay particles can even molecularly bond with the water (weak bonds) and that's what makes clay so good at being a sealant.
All that aside, a human body is quite complicated and rarely contains pure water. I would imagine if you were extracting water that was contained in cells, it would take substantial effort/time for the water to pass through the permeable membranes.
If you've got an hour to spare, I could imagine using the attractive nature of water reimancy like "drying" or like setting aside the body (living or dead) in a very hot and dry place to dry it out. It might be a little faster than naturally drying out meat but I don't see it happening in a matter of minutes.
Similarly with living bodies, I could see the water reimancer trying to target the most 'water-like' parts of a body or sensitive parts (like eyeballs) and effectively drying them out. But if you're going to try to 'attract' blood using water reimancy... well blood isn't water. That would be my conclusion. You might have marginal success, but I think it's much better to use reimancy on the pure element rather than some mixture. Mixtures are better left for para-elements. One could say that ice is technically H2O, but on Mizahar it's still regarded as a para-element.
Anyways, those are just my own reasonings and wanting to keep in mind the game balance. It might also be more available to those at expert/master level.
