Silvering: This property can only be applied to missile weapons. Any ammunition fired from a silvering weapon becomes alchemical silver until it hits something, allowing it to overcome the damage reduction of creatures such as lycanthropes. If an arrow, bolt or bullet is retrieved after being fired, it is normal and remains so unless it is fired again from a silvering weapon
Faint transmutation; CL 7th; Craft Magic Arms and Armor, 10 ranks Craft (alchemy); Price +1 bonus
Adamantine: This property can only be applied to missile weapons. Five times per day, on command, the weapon can transform an arrow, bolt, or bullet fired from it into adamantine. The missile retains this property until it the end of its flight, at which point it becomes normal again. A missile transformed in this manner is treated as adamantine for purposes of overcoming hardness and damage reduction.
Faint transmutation; CL 11th; Craft Magic Arms and Armor, 15 ranks Craft (alchemy); Price +1 bonus
Should adamantine be a +2 bonus, and can anyone think of a prerequisite for it other than ranks in Alchemy? Alchemy makes better sense for silvering, but I can’t find a spell that transmutes lead into gold or whatnot. Maybe a force effect…?
