Agar Atoll

Agar Atoll is a hidden island in the Arc region of the Wushanko Isles. Travelling to the island requires finding a message in a bottle on the beach right next to the southern dock exit on Goshima. It can be investigated to receive a treasure map.

While carrying the map in the inventory, players can talk to Quartermaster Gully and will be asked if they agree to travel to the uncharted isle.

On the island, players can talk to Salmon Ella to receive one taijitu.
