This page offers a guide on how to find all books of knowledge in Gullnámar, in the Dawn of Ragnarök DLC.

There are 3 books of knowledge in Gullnámar: Rage Axe, Knockback Arrow and Explosive Retreat.

Rage Axe

The Rage Axe Book of Knowledge can be found in Uldar. More specifically it’s found in a large room to the right of the lava waterfall, in the southern area of Uldar. It’s behind a locked door and to open it, you’ll need to use the light projector in the middle of the lava. To use the projector, you’ll first need to activate the Power of Muspelheim. Once you’ve done so, use the projector and aim the light at the splitter above the door. This isn’t the door to the room with the book of knowledge though. The door to the left of this one has also opened up and its in there at you’ll find the Rage Axe book of knowledge.

Knockback Arrow

This Book of Knowledge is found on the upper level in the main area of Old City in Uldar. Look for the large crane and then climb up onto the area behind it. Here, you’ll find a light projector. The first thing you’ll want to do is aim the projector at the target above to the door to open it up. Then, to the right, you’ll find the orb amongst some flaming sticks. Pick it up and take it through the opened to door into a room with another projector.

Place the orb in the projector and head back outside. This time, aim the outside projector at the inside projector. This will cause the door to close, but the light can still pass through it. Don’t worry though, there’s an open window above the door that you can use to climb back into the locked room.

Aim the second projector at the target above the door facing east. When this door opens, you can pass through and collect the Knockback Arrow book of knowledge.

(1 of 2) Use the projector and aim it at the projector inside - this will cause the door to shut.

Explosive Retreat

This book of knowledge can be found on the lower level of the Hreidmar Palace mountain. The first thing you’ll need to do is search for the orb. It can be found sitting on top of a wooden crate in the courtyard. Pick it up and place it in the light projector in front of the small building.

Place the orb in the projector.

Once you’ve placed the orb in the projector, interact with it and angle the green stream of light at the target above the door. Right now, there’s no actual light so the door won’t open so you’ll need to head behind the two splitters to find another light projector. This one does contain some energy so when you aim it at the splitter it’ll shoot out energy at the splitter in front, which will then direct energy to the orb you just placed.

When the door is opened, you’ll be able to head into the small building to obtain the Explosive Retreat book of knowledge.

Find the second light emitter and shoot it at the splitter up ahead.
