Cave Island is a tiny island located in the Second Sea. Despite its small size, it is notable for containing three hidden chests, making it a useful spot for quick chest farming.

The island contains:

• A Silver Chest on one side of the large main cave

• A Gold Chest on the grassy top

• A Diamond Chest hidden behind a partial wall in the upper room

Cave Island is located in a remote area of the Second Sea, east of Kingdom of Rose’s docks.

About the Upper Cave:
Upper Cave is a hidden room inside Cave Island, accessible through a small square opening in the ceiling near one of the cave walls, making it easy to miss without careful exploration.

This upper room is one of the five possible spawn locations for the Blue Flower, which appears on one side of the mint-green grassy carpet. The Blue Flower only spawns at night.

The room also contains a Diamond Chest hidden behind a partial wall.
