You may be surprised to learn you’re not the first person to be stranded on the Island. Indeed, you’ll come across notes left by a number of other survivors. Here’s where to find all the Explorer Notes in Ark Survival Ascended to get the beneficial buffs they confer.

How Many Explorer Notes are in Ark Survival Ascended?

There are 125 Explorer Notes and 100 Dossiers scattered throughout the Island map. Though categorized differently than the regular notes, Dossiers are labeled under Explorer Notes, and required when trying to find them all.

How to Find Explorer Notes

These fragments of knowledge are found in chests. Some are fancy while others are simple, but they’re often denoted by ruins, such as columns or archways crafted from ancient bricks. The nice thing is you can add most of the coordinates I’ve listed below onto your map as waypoints, which will lead you directly to the chests and the Explorer Notes inside them.

However, a number of notes are found in the various caves. I’ve noted which ones these are, as the coordinates won’t lead you to the correct location, unfortunately. For these, you must head to the cave entrance and make your way through it to find them. Once inside, the coordinates will lead you to the correct place — just make sure you know which is which when putting them on your map.

What do Explorer Notes do?

When you find an Explorer Note, not only do you learn something new about the Island, the creatures in the area, or a piece of technology, you also get a 100% Experience Boost for 10 minutes. If you get another note within that time, an additional 10 minutes stacks. I strongly suggest you bring your main dino with you that you want to level, as you’ll gain experience nonstop when collecting Explorer Notes.

All Boss Dossier Notes

You obtain four Dossiers by defeating the various bosses on the Island. The notes are transmitted as holograms and describe the boss you just killed.

  • Broodmother
  • Megapithecus
  • Dragon
  • Overseer

What Happens if You Get All Explorer Notes in Ark?

Gathering all Explorer Notes and Dossiers on The Island earns you a 10-level increase to your character. This goes past the level max, giving you further opportunities to overpower other tribes and dinosaurs. The level bonus is on top of all the EXP bonuses you get when collecting the individual notes.

Is There a Command to Get All Explorer Notes?

If you’re struggling to gather all Explorer Notes or already achieved this feat in a previous version of the game, then you may be interested in using the command console to obtain all of them.

  • Open the command console.
  • Enter the command cheat GiveAllExplorerNotes.
  • Close the console.

The game may freeze for a few minutes if you need many of the notes unlocked as the system processes through the request. You’ll now have all Explorer Notes unlocked and available to view in your journal. This doesn’t specify if you’ll obtain the EXP buff along with the level increase, so you may want to experiment with unlocking a specific note first if that’s what your aim is.

Those are all the locations for Explorer Notes and Dossiers in Ark Survival Ascended. For more on the game, such as updated cave entrances or how to farm metal and oil, check out our guide hub.
