Anno 1800 Wiki

Diving is a new feature in Anno 1800 added with the Sunken Treasures DLC. It requires a special ship called salvager, which can be obtained from Old Nate soon after settling on Crown Falls in Cape Trelawney. Diving lets the player find various items or find scrap, used to craft special items at Old Nate's workshop.

First thing to do when attempting to dive for treasures is to find a spot appropriate for diving - you can't dive everywhere. There are three ways of finding diving spots:

  • Radars
  • Treasure maps
  • Diving quests

Radars

Radars are items which after being equipped and activated on a salvager indicate the closest diving spots. It is recommended to always have some sort of radar equipped in your salvager, even when using the other two ways of finding diving spots. You can craft them at Old Nate's workshop in Cape Trelawney. There are three radars of different rarity, the only difference between them is the distance on which they are effective. Legendary radar can detect diving spots much further away from the ship than those of lower rarity.

Using radars and how to dive

If the radar locates a diving spot, white waves appear next to the salvager (when salvager is active), indicating in which direction and how close away from the salvager the treasure is. Following the direction from which the wave signal is coming from, you will get closer to the treasure. Waves will be getting smaller until finally you reach the diving spot, which is marked by a white spot in the sea with a circle around it. Navigate the salvager into this position, when being in the correct spot, a special icon will appear above the ship and the diving button in the ship's UI will become active.

Clicking on the diving button starts the diving process, which lasts 10 seconds, after that time the treasures will be loaded on the salvager. The rewards you get depend on the region the salvager is in and on what types of items are equipped on the ship (to see what items can be used on salvager to affect the outcome of diving click here).

Treasure maps

The second way of finding diving spots is activating a treasure map which generates a special diving spot somewhere in the particular region. Opening a treasure map acts as starting a quest, which lasts for 60 minutes, that's the time the player has to find the treasure.

Map types and obtaining them

There three rarities of treasure maps: rare, epic and legendary, the better rarity of the map means the higher chance for finding a rarer item. Every map also corresponds to the particular region and particular reward type (machines, animals or artefacts). Having 4 regions, 3 rarities and 3 types of rewards means there are actually 36 different treasure maps in the game. The rarity and the region of the map can be recognised from how the map looks, as indicated by the icons below. Only the type of reward has to be determined by checking the description of the map.

You can obtain treasure maps by buying them from neutral traders or pirates like Old Nate, Isabel Sarmento or Anne Harlow. Sometimes they are offered as quest rewards, they can also be found during expeditions or gained from exhibitions at the World's Fair.

Treasure maps mechanics

To use a treasure map you need to click on it to activate the quest. Then the map will open showing you an island and an X spot nearby which indicates the treasure, there is also an icon in bottom right corner of the map which corresponds to the region where the treasure can be found. Then you need to find the diving spot, either by recognising the place shown by the map (use of the trade route menu is recommended) or using a radar to find the spot more easily (especially recommended in case of some tricky maps where there might be no island shown). In case of spots generated by treasure maps the signals from the radar are yellow making them easily distinguishable from regular diving spots. Treasure location is also marked by seagulls flying above it and bubbles visible on the surface ot the sea. It helps to make sure you found the right spot if you try to locate the it on your own.

Diving quests

Sometimes you can also get diving quests from Old Nate or from people in the Arctic. They usually require you to find something in specific spots which are revealed to you with the quest, therefore radars are rarely needed. However, in some cases you need to avoid sea mines or find the spot yourself, then radars are necessary. Besides finding the diving spot, they can also find mines which are indicated by red colour of signals and spots.

Scrap

Scrap is a very typical reward for diving, it is used to craft many useful items at Old Nate's workshop in Cape Trelawney. There are three types of scrap, each used for specific sets of items. Regular scrap is found very often while special scrap is rare and the most valuable. To read more about scrap and crafting click here.
