Technically, because the game automatically gives Geralt the necessary ingredients to craft Thunderbolt as part of a tutorial, Thunderbolt has no crafting requirements, as far as the player should be concerned.
|Items which Require Thunderbolt||Number of Thunderbolt Required|
Both the formula and the ingredients required to make Thunderbolt are automatically given to Geralt as part of the main quest "The Beast of White Orchard" after Geralt speaks to Vesemir outside of the inn with a plan to kill the Griffin. After Vesemir leaves, a tutorial begins which instructs Geralt on how to craft potions. The tutorial involves Geralt crafting Thunderbolt, and gives him all necessary supplies to do so. Whether or not the player's having tutorials disabled in the game settings prevents Geralt from obtaining Thunderbolt, or its crafting ingredients automatically is not yet known.
