Before traveling into the wilds of the Northern Realms, it is wise for you to fully grasp the abilities of Geralt of Rivia and Cirilla. Movement, fighting with the steel and silver swords of the witcher, and mastering the use of Signs is only the beginning. Further your knowledge of alchemy, crafting, witcher abilities, skills, leveling, weapon and armor maintenance, meditation and preparation, the economy of trading, and the variety of interesting (and dangerous) environmental areas from monster nests to points of interest. Don’t leave Kaer Morhen without a full understanding of this information.
