In Assassins Creed Valhalla there are a couple of ways to get new abilities. One of these methods is by collecting books of knowledge, which are not always easy to figure out how to obtain. The one at Crepelgate, for example, while easy, isn’t overly obvious.
We’ll show you how to get Crepelgate Fort Book of Knowledge in Assassins Creed Valhalla. Here’s a full detailed guide on how to get into Crepelgate Fort and how to find the book of knowledge.
Finding a way into the Crepelgate fort building
The first thing you need to do is figure out how to get into the fort, something which had me looking for ways to unblock the locked door for ages, before coming to realize, that’s not how you get in there.

Don’t waste your time and arrows shooting through the windows. I was convinced that there were boxes blocking the door and spent ages trying to shoot these imaginary boxes, don’t make my mistake.
Find the gap in the tower
Connected to the building is a wooden tower; at the base of it there is a small gap which you can get under.

Go underneath the tower, through the gap pictured above, and look up and to your left.
You will notice an open window which you can climb through, again I didn’t find this straight away and somehow found myself coming back a few times before I spotted it.

Once you have gone throthe window, you will see a rack that can be moved, drag it out of the way and you will notice it was covering a hole which leads to the bottom floor.
Drop down to the bottom floor and you will see the book of knowledge at the end of the room.

Once you have picked up the new ability, don’t go back the way you came, simply hit the door and you will be able to leave out of the door which was previously barred.

There are many other books of knowledge in Assassins Creed Valhalla, besides the Creplegate Fort book of knowledge.
I recommend finding as many of them as early on as possible, as the abilities can make a huge difference to your chances of survival, during main story missions or raids.
