All Collectibles in The Applecore

Odin's Raven: Deep within the mine, in the large room where Atreus pulls a lever to drop Soundstone into a waterway. After solving the puzzle and crossing, look north to a ledge you can shimmy across. The Raven is on a beam to the north.

Artifact - Things Left Behind - Althjof’s Statue: After unlocking an elevator via a switch with the Blades of Chaos and climbing a chain, you'll see debris across a gap. In the area where you drop down with the chain, hit the red pot near the debris to clear it. Defeat the enemies in the path behind the debris, then go through the door to find a materials chest and the Artifact.

Artifact - Things Left Behind - Durinn’s Stone Statue: After getting your first Relic and reaching an area where you pull a chain for a zipline (after clearing Soundstone), you'll see a wooden walkway end near a small waterfall. Use the grapple point to cross the gap, then drop off the ledge. Have Atreus clear the Soundstone deposit, and grab the Artifact behind it.

Artifact - Kvasir Poem - Sanguinity (Requires Draupnir Spear): Return to The Applecore after acquiring the Draupnir Spear. From the Applecore Descent Mystic Gateway, head north then east. Throw the Draupnir Spear at a point in the wall to create a handhold and climb up. Look northeast for another point in the rock, throw the Draupnir Spear, and detonate it to destroy the rock. The Kvasir Poem artifact is on the ground to your right.

Legendary Chest 1: Located in the same room as the Draugr Hole. Clear the room first, then find the chest on one side. This chest contains the Axe Attachment - Fortified Frost Knob.

Legendary Chest 2: Accessible upon emerging from The Applecore into the Jarnsmida Pitmines on your second visit. To the left, you'll find a rune slate. Interacting with it reveals a word that Freya or Atreus can interact with, uncovering the Legendary Chest behind the wall to its right. This chest contains the Banahogg Knob axe attachment.

Lore - Rune Read - The Vault: After arriving at Sindri’s blacksmith shop via boat, proceed to the first grapple point. Instead of crossing, look for a wooden wall with Soundstone. Have Atreus shoot the Soundstone to reveal the Rune Read.

Lore - Lore Marker - Cooperation: During your normal progression through The Applecore, you'll reach a split path before your first Draugr fight. Head west to a wooden wall, break it down, and drop down the ledge behind it to find the Lore Marker.

Treasure Map - Demise of Dagestr: After acquiring the Draupnir Spear and completing the main quest Forging Destiny, return to The Applecore. Ride a lift down, turn southwest then northwest, and kill the Grim and Nokken. At a fork, stick left and follow the path to a chamber with Revenants. Kill them, then search the southern end for a ledge too high to climb. Throw the Draupnir Spear into the wall to climb up, and find the Treasure Map - Demise of Dagestr on the ground.

Draugr Hole: Located in the same room as the first Legendary Chest.

Buried Treasure: The source text does not specify the location of the Buried Treasure.

Yggdrasil Rift: The source text does not specify the location of the Yggdrasil Rift.
