Assassin’s Creed Valhalla: All Book Of Knowledge Locations (Abilities)

Get the locations of all Book of Knowledge in Assassin's Creed Valhalla.

Similar to the previous titles of the franchise, even Assassin’s Creed Valhalla offers several abilities that Eivor can use during combat, However, unlike the previous installments, abilities in this game cannot be unlocked by gaining experience. Instead, you will have to unlock them by exploring the map of Norway and England. Unlike the skills that you can activate in Skill Tree by gaining experience, you will have to find All Book of Knowledge for unlocking abilities in AC Valhalla. These books have the wisdom that helps your character Eivor learn new abilities that you can then equip to use during combats. In this AC Valhalla all Book of Knowledge locations guide, we will enlist all the abilities that we have unlocked so far, and where and how to find them.

Before getting into the list of all abilities in AC Valhalla, we want to inform you that it is an in-progress guide, and we will keep updating it as soon as we find new abilities across the map with their details.

How Book of Knowledge and Abilities System Works in Assassin’s Creed Valhalla

Every Book of Knowledge contains wisdom that lets Eivor learn new abilities. There are several of them well hidden, usually behind a small puzzle or hostile area across the maps. There are two books for each ability in the game. Finding the second book for the same ability will upgrade the ability and make it significantly stronger in terms of stats. There is no order of collecting books for an upgrade. You can collect them in any order and still the ability will be upgraded when you find the second book.

You will get either a ranged or a melee attack ability by finding these Book of Knowledge. Once unlocked, you can assign the available abilities from the Ability menu. From the Ability menu screen, you can assign the best ones to Eivor. You can only assign 4 abilities at most for each category. Hence, try experimenting with different combinations until you find the best suitable for you according to your game style.

Focus of the Nornir

The Focus of the Nornir is a ranged ability that lets Eivor slow down the time while using a bow. This not only helps Eivor to aim perfectly, but also take down multiple enemies within a flash of time. The in-game description of this ability reads, “Use the power of the Nornir to aim and shoot at your enemies with fateful speed.” The in-game description for the upgrade of this ability reads, “Each killed enemy increases damage dealt.”

First Book’s Location

The first book’s location for the Focus of Nornir ability is Offchurch located in the southwest part of Ledecestrescire. The area is loaded with enemies and it will be very challenging to get this book. The book is inside the large main crypt right at the center of the area. When you enter this chapel, take down all the enemies there.

While clearing the chapel, keep an eye for a small opening on the right side. It will be somewhere after half of the chapel’s room is over. Crawl through the opening to get inside the chamber that holds the book.

Second Book’s Location

The second book is located in Bolingbroc Castle. It is to the east of Lincoln city in Lincolnscire. Once inside the area, head north. When you follow the wall that has spiked logs on it, you will find a fort. Keep an eye out for an opening towards your left. It will be next to a pile of leaves. Simply enter the opening to get to the Book of Knowledge for Focus of the Nornir ability upgrade.
