On a successful attack with a silvered slashing or piercing weapon, the wielder takes a –1 penalty on the damage roll (with a minimum of 1 point of damage). The alchemical silvering process can’t be applied to nonmetal items, and it doesn’t work on rare metals such as adamantine, cold iron, and mithril.
