Just like heat storing items, there can be water storing items.

 

A bit pointless you might say, but I find it interesting for storing water of special places.

For instance, a bottle containing only water collected from Angien's Shrine, or raindrops collected from the depths of Necrovion - 'tainted' water.

 

 

RP purposes only, not really worthwhile for something else.

I like it......I had suggested this kind of thing sometime back but...aint got through....

Or, resource containers of any sort.   "Pouch" could store resources you collect, be it water or lumber or fenths, "outside" your default inventory.

 

As much as I dislike "resourse splitting" in general, it's an option that's still valid to consider.

So similar to heat jars, these items would drain resources over time?

With a good container, water doesn't dissipate, so no, fixed amount of water would remain in the bottle.
