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

Axe Blizzard – East Anglia, just southeast of Northwic

This Book of Knowledge is atop an abandoned church building.

Harpoon Impalement – Venonis, Ledercesterescire

To find this Book of Knowledge, descend a ladder in the middle of the ruin to enter the tomb. Continue through until you reach a breakable wall, pass through, enter water and up the other side, blow up another breakable wall, grab the book.

Raven Distraction – Tonnastadir, Ledercesterescire

You’ll need to find the key first, which is due east of the tomb entrance.

Piercing Shot – Templeborough Castle

This one is located in the central castle area. Use your Odin’s Sight to pulse and you’ll find it easy enough.
