Final Fantasy XVI The Rising Tide introduced four new Eikon power attachments for Clive to craft. The only catch is that they require materials that can only be found in Mysidia, and in fixed quantities at that. Here's where you'll find Aquamarines in FF16.
Final Fantasy 16: The Rising Tide – All Aquamarine Locations
Aquamarine will only appear on the Mysidia map after you complete the What Ails You sidequest in Haven. The Blacksmith will reward you with a stone that can detect Aquamarine on the map. You should hear a drop of water if you’re nearby, but these things also grow quite brightly.
Aquamarine locations vary based on difficulty. I found that harder difficulties, such as Final Fantasy and Action mode, had more Aquamarines in monster bellies. This means you have to defeat a lot of nasties to get them.
You won’t find all the Aquamarines you need to craft all four Leviathan attachments at once, so only craft the ones you know you’ll use. With that said, here are all of the Aquamarine locations I’ve found in Final Fantasy 16 and exactly where you can find them.
