Cold iron

Cold iron was a type of iron mined deep underground. It was forged using a special process at lower temperatures than normal iron or steel in order to preserve its delicate properties. It was famed for its efficacy against fey creatures, and was also effective against eladrin and demons. Some sources stated that ghasts were more easily harmed from cold iron weapons.
