The Seahorse Vase
Green-black coral is arranged in layers to make a seahorse vase that comes filled with saltwater. The seahorse rests on its tail when placed on a flat surface.
The Seahorse Vase can continually supply any liquid it has been filled with. Each time after pouring, regardless of the amount, roll a d6. On a 1, the vase has emptied and will suddenly feel lighter. Only once emptied of its prior contents, the vase can be refilled by submersion in any liquid, and it will supply that liquid until it empties again.
