Assassin’s Creed Valhalla Clogher is one of the landmarks in Ulster; the fourth Irish area in the Wrath of the Druids DLC, and by exploring it you’ll be able to unlock the Smoke Bomb Arrow Ability for Eivor.
The Assassin’s Creed Valhalla Wrath Of Druids Clogher Book Of Knowledge also counts as a collectible you’ll need to get if you aim for 100% completion in the game, and below I’ll tell you how to get this Ability in the first DLC because it is one of the trickiest collectibles.
Similar to Aileach Gear we covered earlier.
As usual, let’s start with the exact location of the Clogher Ability in Ulster.
On my map below, you can see that Clogher is found on the central island in Ulster, just west of Sleeve Gallion.
As you arrive at this location, you’ll notice that the village is deserted.
Now, if you scan the area the Book Of Knowledge in Clogher appears underground.
So, finding the entrance is the key here. Except that this entrance is a bit difficult to spot.
Here is what you need to do.
How To Get The Clogher Book Of Knowledge (Ulster Wealth)
Head to the upper side of the village and try to position yourself on top of the icon showing the Book Of Knowledge.
You should be in front of a door, and if you turn left you’ll notice several red jars.
In my screenshot above you can see that they are found in front of a shack with some hay inside.
Pick one of them.
Now go around the shack in the screenshot (left side), and descend to the lower level.
You should be able to spot a rather large tree and behind it, a wall covered with ivy.
Look closer and you’ll see a breakable wall (pictured).
At this point, you should be around 47 meters away from the Clogher Wealth.
Place the jar in front of the wall, then shoot it.
Next, get inside the cave and in the first room pull the large stone on the left side.
Go behind it to collect the Book of Knowledge which unlocks the Smoke Bomb Arrow Ability.
And that’s it, Viking. You just found the Assassin’s Creed Valhalla Wrath Of Druids Clogher Book Of Knowledge in the first DLC of the video game developed by Ubisoft.
