Here are the details, via Bandai Namco Europe:
Klaus is a member of the Golden Dawn, the strongest of the nine squads of the order of the Magic Knights. He takes on the Support role. As a battle strategist, he can control the battlefield by dividing the fighting-line to his liking. His attacks have a dual purpose inflicting damage and confining enemy’s movements. This character will best be used as a support for a powerful Ranged magician.
The Grimoire Cards will allow players to maximize the effectiveness of their character’s abilities. Every Magic Knight has access to one of three unique Decks, each suiting different play-styles, granting them passive enhancements and ability improvements. From this deck, players can further personalize their character by choosing four Grimoire Cards to give them access to additional abilities.
Black Clover: Quartet Knights is due out for PlayStation 4 on September 13 in Japan, and for PlayStation 4 and PC via Steam on September 14 in the Americas and Europe.
