Treasure map is an item found in the message in a bottle on the north-west beach of Waiko behind Sojobo. The map leads the player to Springbreak Island, where they can meet TzHaar-Ga'al-Knot and receive one Taijitu.
The message in a bottle that contains this treasure map is currently visible. (wrong?) Once a message in a bottle is found and when a player has walked near its spawn location when it was visible it will always be visible, unless the message in the bottle or its treasure map is in the player's bank or inventory.
Please save me. It's cold here. The pressure of being alone is unbearable.-Captain-Knot
