Manganese

• You can find this item in drifting boxes on the ocean’s surface.
• You can find it in treasure chests in sunken shipwrecks.
• You can find manganese nodes on the ocean’s floor and mine them with a pickaxe.

Drifting Boxes

As you sail the ocean, there will be two types of drifting boxes that will spawn near you. They have random contents of two types. The square ornate boxes yield crafting materials when you pick them up, while the barrels give you trade goods.

Treasure Chests in Sunken Ships

Use your Underwater Detection system as you sail your ship. When the circles turn orange, look for a bright blue spot in the depths beneath the surface. There are many sunken small ships on the ocean’s floor. Inside, you will find a large treasure chest containing crafting materials.

Manganese Nodes

You will find Manganese Nodes at the bottom of the ocean. There are multiple locations. One easy-to-access spot is at the Great Hydrothermal Vents in the South Sea.

The Blooms Beneath the Waves Abyss Cresset from the Scenic View Challenges is nearby, so you can return to this spot quite easily whenever you wish.
