Silversheen

This substance can be applied to a weapon as a standard action. It will give the weapon the properties of alchemical silver for 1 hour, replacing the properties of any other special material it might have. For example, a +1 holy adamantine longsword becomes a +1 holy silver longsword for the duration of the effect. One vial will coat a single melee weapon or 20 units of ammunition.
