In The Blood of Dawnwalker, Ability Manuals are special books that unlock new skills and abilities in your Swordmastery and Witchcraft skill trees. Each manual corresponds to a specific ability or perk, allowing you to train it once you've read the required book.
Manuals can be found in treasure chests, Bandit Camps, Soldier Camps, Haunted Sites, Ancient Circles, and other points of interest. They can also be obtained as quest rewards, dropped by enemies, or purchased from specialised merchants such as Swordmastery Teachers and Witchcraft Vendors.
To use an Ability Manual, open your inventory, select the book, and read it. This unlocks the corresponding skill in the development tree, but doesn't grant the ability immediately. You must still visit a Shrine and spend the required Skill Points and, in most cases, an additional in-game Time Segment to learn it.
Ability Manuals are only required for certain skills in the Swordmastery and Witchcraft trees. The Vampirism skill tree works differently, as its abilities are unlocked through increasing your Corruption Level by consuming blood.
