Ambergris

• You can find Ambergris in treasure chests in sunken ships. Their contents is randomized.
• You can get Ambergris as random rewards from floating boxes, but this is rare, compared to Malachite and Shiny Ore.
• You can mine Ambergris from Ambergris deposits around The Sleeping Collosus Beneath the Waves.
• You can send a Mission Dispatch to Bergen Island

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.

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.

The Sleeping Collosus Beneath the Waves

Around this Abyss Cresset, part of the Scenic Views Challenges, you will find several Ambergris Nodes. They are bright orange and flash even brighter when you point the lantern at them.

Beware of the many sea monsters in the area. It may be difficult to farm these nodes. If you have the Enhanced Propulsion Breathing Device, you can afford to use your farming suit with Blessing of the Earth III. And use the best enhanced mining tool available to you for the best results.

Mission Dispatch

After you pioneer Bergen Island, you can send Mission Dispatch there that has a chance to yield Ambergris. The mission is relatively short and inexpensive, especially if you are past the main story of the game and have expanded your camp and have plenty of workers and resources.

Bergen Island is unlocked for Pioneering after you defeat Rohan Cooper, part of the Cave of Sorrow questline.
