The Fluvian jar, its volume magically increased by some Divine enchantment, will contain 100 draughts of water when filled from a water location.

If the contents of the jar are poured on an adventurer with the stink affliction, the smell will be washed away; the jar will then become entirely empty, however.
This cylindrical artefact of polished prismatic crystal was once on sale at the Shop of Wonders in Delos, but has since been discontinued.
