The Assassin’s Creed Valhalla gameplay experience goes far beyond the central story of Eivor, with the vast open-world being filled with Mysteries, from Treasures of Britain to Animus Anomalies.
Each Treasure of Britain builds to a superior, final reward, with the Deoraby Spar Cavern treasure contributing to your pursuit of the legendary sword Excalibur.
However, there’s a lot more to be found in Deoraby Spar Cavern in AC Valhalla. So here, we’re going through everything that you can find here, as well as where you can find the Treasure of Britain.
What is the reward for collecting a Treasure of Britain?

In order to unlock Excalibur in Assassin’s Creed Valhalla, you need to collect all 11 Treasure of Britain tablets throughout the game. Many are located on the map, while a few are held by powerful Zealots that must be found and defeated.
That means the Treasure of Britain in Deoraby Spar Cavern is just one piece of the puzzle, but that’s not all you’ll get for exploring this location. You’ll also be rewarded a Skill Point, a quick increase in Power, for collecting the Treasure of Britain at Deoraby Spar Cavern.
On top of that, there are a few treasure chests throughout this cave that will have much-needed resources for upgrading your equipment. You can also smash pots as you’re making your way through the area to score a few extra silver or trinkets in the remnants.
Where is Deoraby Spar Cavern?

You’ll find Deoraby Spar Cavern in the northern part of Snotinghamscire, and it’s not far from the region’s eastern border. The fastest way to reach it is to fast travel to the synchronization at The Sleeping Jotun, if you’ve already discovered and activated it.

If you haven’t, you can follow the river on the eastern edge of Snotinghamscire towards a dead end that’s actually quite close to Deoraby Spar Cavern. The game has a Suggested Power of 250 for operating in Snotinghamscire, but that’s not a requirement.
If you’re close to that Power you shouldn’t have too much trouble. Even if you’re lower, there are no enemies at Deoraby Spar Cavern. Just make sure to save often on your way in if you’re underpowered, just in case you encounter a random enemy you can’t tackle.
How do you get through Deoraby Spar Cavern to the Treasure of Britain?

Finding the entrance to Deoraby Spar Cavern isn’t difficult, but knowing exactly where to jump and how to traverse this area can be. There are also some treasure chests and resources you’ll want to snag along the way.
Odin Sight is going to be your friend here. Be sure to activate it often so you don’t miss something to loot or collect. As you first enter, there are a few rocks that can be destroyed with your weapon to collect some Iron Ore.

On the left in that entrance area, there is a cliff you’ll need to jump to in order to progress. In the above photo, jump first on the rock to the right and then to the cliff edge just above Eivor’s head to move on to the next area.
After you slide through a crack in the wall, you’ll see an area where a skeleton is leaned against a concrete platform. Be sure to loot that skeleton, as it’s holding a key you need to continue through the cave, but don’t mis the lootable urns beside it either.

Head through the locked door, which your key will grant you access to, and you’ll reach the next area of Deoraby Spar Cavern. There’s a treasure to your left, and a note and some Titanium to collect on the right.

First follow the path to the left around to the treasure, and then you’ll need to leap across the central cavern to reach the area on the right with the large statue. Collect the Titanium, and then you’ll need to climb behind the statue on that side to continue on.

You’ll need to jump onto a small branch protruding from the cliff, and then follow the rocky edge on the right side of this next large statue. Jump across to the statue and then to the column, and from there use the bluish stalagmite and the ceiling’s largest two stalactites to reach the second treasure chest.

Loot that chest, and finally turn to the fallen statue on the left of the chest. Climb up that statue, and now be able to pass into the room containing the Treasure of Britain.

You’ll earn a Skill Point, increasing your Power, and a Mysterious Whetstone Tablet will be added to your inventory. This is part of the full group of tablets needed for Excalibur.

With this collected, you’ll have successfully completed the Treasure of Britain at Deoraby Spar Cavern. This knocks out one of the Mysteries in Snotinghamscire and will get you one step closer to Excalibur.
After you’ve collected the tablet, there is a door to the left that leads to the exit. Use your weapon to break the piece barring the door and follow that way out, dropping down to break some jars and get a little more loot in the final cavern as you exit.
