Weapon Blanch

These alchemical powders have a gritty consistency. When poured on a weapon and placed over a hot flame for a full round, they melt and form a temporary coating on the weapon. The blanching gives the weapon the ability to bypass one kind of material-based damage reduction, such as adamantine, cold iron, or silver. The blanching remains effective until the weapon makes a successful attack. Each dose of blanching can coat one weapon or up to 10 pieces of ammunition. Only one kind of weapon blanch can be on a weapon at one time, though a weapon made of one special material (such as adamantine) can have a different material blanch (such as silver), and counts as both materials for the first successful hit.
