I think I want a hydrokinetic char, but I'd like some advice on the specifics.

I don't think I want to go full bloodbender, seems a bit much like mind control tbh, but I do think I'd like to be able to pull water from things like blood, air, whatever. It has the potential to be a really fun take on the power in this setting to sense, manipulate, and weaponize water in an environment where the stuff is both scarce and valuable. The question is would I then be able to go with the standard waterbender package of manipulating water into ice? Sharpening it into blades thin enough to cut? What about other liquids like alcohol or idk tranquillizer fluids? I can think of some pretty fun uses of slinging highly flammable substances around in a firefight or pulling poison from a wound, but I dont want to be too overpowered or too useless so suggestions pls?
