Blue-green spiral shell

A blue-green spiral shell (shortname: harbourshell) is a vital tool for the littoral infiltrator. Blessed with the oceanic detection ability, the shell informs its listener whether a shipbound adventurer is at sea, or, if moored, what harbour they are currently docked at. It is themed for the Empire of the Sea.
