The game features responsive, advanced AI and dynamic environments. The day and night cycle influences some monsters and their powers, similar to the common mythological motif of a werewolf gaining powers during the night of a full moon. The game also features a dynamic beard growth system, in which the beard of the playable character Geralt grows as he spends time in the world. Ciri, an exceptional sword fighter with mythical powers from the Witcher novels, is a playable character in the game. Gwent is an in-game collectable card game, which replaces the dice games from the previous two Witcher titles.
