If you're not sure what abilities work well together, try one of the preset decks. Press N to open your Ability Wheel and click the Decks tab on the left side of the screen.
Decks are optional, pre-suggested templates of complementing abilities. There are eleven unique decks for your faction, representing the various specialisations they have taken up to combat darkness—and each other.
Choose a deck to see its description, weapon requirements, and the locations of the abilities on the Ability Wheel.
In addition to the benefits of a deck’s ability synergies, completing a deck will earn unique character rewards.
