Geralt will stumble across various diagrams, recipes, and schematics for crafting his hunting implements when traversing The Continent. The amount is vast and varied, but we have searched far and wide, from the rectories of The Mage’s Tower to the deepest parts of Kaer Morhen, through tangled tombs to dank dungeons.
Crafting allows Geralt to create some of the most powerful items in the game; most are more potent than what you can find while adventuring. It also allows him to get the upper hand or, at the very least, level the playing field against many of the monsters encountered.
The assortment of knowledge is now being passed onto you Witcher, use this information as you will, but know that the potions and decoctions lie on another page of the tome.
My earliest memories of gaming started at an early age, playing my Atari 2600 so much in one sitting that it caught fire. Gaming has been my passion since that fateful day and will continue to be a driving force in my life. There aren't many types of games that I won't play, except for the TMNT NES. I still have PTSD from that water level as a child.
