This highly useful item for cooks and gardeners is obtained by the unlikely activity of throwing full water pitchers at a water elemental (double click pitcher, target water elemental). Most pitchers unfortunately will smash (‘The water pitcher has shattered’), but eventually you will see the message ‘The water elemental has thrown a magical decanter back to you’.
Each water elemental only has one magical decanter.
Once obtained the decanter must be linked to a water source – usually a water trough. Whilever you are within reach of this source the decanter will auto refill from it.
