Where to get the AC Valhalla Grimes Graves treasure
The entrance to Grimes Graves is covered by a makeshift shelter and you'll need to climb down into the pit to access the labyrinth of caves beneath. Luckily, there's a haystack at the bottom which makes it a quick leap to get down there. Once you're safely at the bottom of the pit, head straight across the room and through the door in front of you.
Follow the path ahead and jump across the gap to the other side and go through the door there. You'll need to vault over a couple of obstacles in the doorways here and you should see a table with scrolls and some lootable objects to your right. Keep going until you reach a drop. You'll need to jump across here and follow a narrow ledge around the edge of the cavern. Use the two wooden posts at the end of this to jump to the doorway ahead.
Slide down the short gravel slope here and you should find another table with more lootable objects. It's dark here and hard to see here, but you can use your Odin Sight to see where you need to climb the wall in front of you to continue. Pass a table on your right and slide down into the room ahead. A ladder will allow you to climb up on the far side. Keep following the path ahead, traversing several wooden platforms and posts and you should see a big black flag. Make another series of jumps and you'll finally reach an alcove with a table and various goodies. The Treasure of Britain tablet is among them but you have to smash one of the vases to retrieve it.
