Four new abilities are introduced in the DLC, and each needs two Books of Knowledge to upgrade. This AC Valhalla Dawn Of Ragnarok All Book Of Knowledge Locations guide shows you the location of every single Book of Knowledge in the Ragnarok DLC, with additional information on how to solve all the Light Puzzles.
As with the base game and subsequent expansions, Books of Knowledge have two primary uses. The first Book of Knowledge you discover for an ability will unlock the ability to be used. The second Book of Knowledge you find for that same ability will upgrade the ability to include additional effects. Below is a breakdown of every new ability, what it does, and what the upgrade adds.
Shoots ten electrified arrows in a cone shape, staggering enemies, and launching chain lightning among nearby targets. The upgrade adds additional effects, including interrupting and knocking back enemies.
Shooting a lightning arrow that stuns enemies around the target and attacks them with chain lightning. The upgrade adds an additional effect, stunning all nearby enemies when the initial target falls to the ground.
Perform a series of strong attacks that stuns the enemy. Finishing the attack with R2/RT towards the end launches an additional uppercut. The upgrade adds an additional effect to the finisher aspect of the ability, pushing the target back and striking them with chain lightning.
Jump backs to avoid attacks and launch a lightning strike that deals damages to all enemies within range. The upgrade provides an electric shield for 10 seconds, halving all damage.
