Visiting Archipelago Islands is a great way collect resources, have new adventures, and pick up rarities that you can use to make upgrades on Home Island.
As you progress through Elf Islands, you will get to a point where Home Island is exhausted of its natural resources. That’s when visiting the Archipelago Islands will be essential to gather more logs, sticks, and other resources you will need to continue crafting new items.
Remember that when you are on an Archipelago Island, if you do not complete the island’s final quest, the next Archipelago Island will not open, even if you have reached the required level.
Finally, don't forget that apart from Archipelago Islands, you can also visit Event Islands. These islands open for a limited period of time, so be sure to travel to them and complete all the quests while you can.
