Knowledge Books or Ability are part of the Wealth and can be found in any region of Norway or England in Assassin's Creed Valhalla. These books offer skills that are the different techniques you can use in combat. These abilities fall into two categories: melee attacks and ranged attacks.
These techniques can be an assistance for the phases of infiltration or a means of inflicting damage on your adversaries. You will be able to equip 4 skills of each category - melee or distant - so you will have to make a choice. Moreover, it's possible to increase the level of your aptitude by learning a similar knowledge book.
