Assassin’s Creed Valhalla Wrath of the Druids Clogher Book of Knowledge location

The Assassin’s Creed Valhalla Wrath of the Druids Clogher Book of Knowledge location in Ulster is hidden well. This gold wealth dot contains a valuable ability, too: the smoke bomb arrow (or an upgrade to it, depending on what book the player finds first). Here’s how to get the Book of Knowledge in Clogher in AC Valhalla Wrath of the Druids.

To get the Book of Knowledge in Clogher, Ulster in Wrath of the Druids, players have to go to the west side of Clogher like in the spot in the above picture. It’s a bit below the general ground level of the town, which is what makes this book so much more difficult to track down.

There will be a well-hidden breakable wall underneath some vines. Use the Incendiary Powder Trap ability (the explosive arrow ability from the main game) or a nearby red jar to blow up the door.

Go inside of the cave and there will be a small chest with some silver, luxuries, and a red mask, but, more importantly, it will be near a big moveable stone with handles on it. Move it over and out to make enough room for Eivor to slink through.

Slide inside the hole the rock just made. The Book of Knowledge will be sitting in that little crevice.

Just interact with it to get the ability (or the upgrade to it).

The smoke bomb arrow is useful for stealth and it can be upgrade to light people on fire, too, which might not be the best for stealth. And since it is a piece of wealth, it is required for the “Irish Legend” trophy or achievement which unlocks after clearing every part of Ireland.
