Thunderbolt (scroll)
From Witcher Wiki
The Book of the Thunderbolt
Scroll contains formulae for the following potions and oils:
Thunderbolt: increases damage inflicted on opponents, but makes dodging and parrying impossible
Shrike: Inflicts pain on assailants during combat
Full Moon: Significantly increases maximum Vitality
Vampire Oil: causes increased damage to all types of vampires
This is not actually a book but a scroll, and it's not actually called the Book of the Thunderbolt, sort of. In your inventory, it appears as The Book of the Full Moon, but when you read it, the title is The Book of the Thunderbolt. It contains the formulae for four different potions.
