Fisstech
Fisstech is a powerful drug in The Witcher. Its in-game description simply labels it a strong narcotic, and it is listed among the items Geralt can brew through alchemy.
Like other alchemical preparations, it is made on an alcohol base while meditating at a fire or an inn, provided Geralt knows the recipe or discovers it by experimenting. The formula needs 1 Quebrith, 3 Hydragenum and 1 Vermilion.
