Regularly Check the Bestiary
The Witcher 3: Wild Hunt includes a constantly upgrading, comprehensive bestiary of the many different beasts Geralt will unfortunately cross paths with. Once one of an enemy type is slain, an entry for that particular monster will be added to the bestiary complete with background information, and weaknesses. Considering the vast variety of enemies present in The Witcher 3: Wild Hunt, it’s a good thing that this resource is present, because memorizing every intricacy of every foul creature would be next to impossible.
Of course, the bestiary is completely pointless if players don’t take the time to utilize it. Knowing exactly what sign to cast, as well as what item to use, against a specific foe is invaluable information. As the game progresses, combat will only grow more difficult, and having any type of strategic advantage going into these battles is something definitely worthwhile.
