Next, use the quest marker to find the islet west of the Minacious Isle, which you can get to using a Waverider. Once you're there, climb the mountain and jump down to enter the cave. Use Elemental Sight to find the breakable boulder in the room, then break it using Geo Damage or a claymore. Inside, you'll find a Common Chest containing a Quest Item called Sea Route Log.
Next, use the Waverider to sail in the direction of the constellation in the sky, or southeast. You can simply reference the image above for the exact location of the destination you're looking for. Once you find the islet, climb the rock to loot a Common Chest containing the final Quest Item: A Complete Chart of Ako's Treasure. You can proceed with completing the Treasure Clues for the Broken Isle and Twinning Isle in any order. When you're done with those, you can move on to Where the Treasure Dwells.
