Argentia
Argentia is a blade oil in The Witcher that boosts the damage of Geralt’s silver sword. The trade-off is that it weakens his steel sword while it is in use, so it pays off when the fight calls for silver.
Geralt can brew it while meditating at a fire or an inn if he knows the recipe or works it out by experimenting. The formula takes 1 Rebis, 2 Quebrith and 2 Hydragenum on a grease base, and the finished oil is applied to the blade.
