Cold Iron

TTRPG Fictional · Uncommon · Medieval

Iron mined and worked without the use of fire, hammered cold from the earth and never heated to forging temperature. The process is grueling and the resulting metal weaker than properly forged iron, but its effect on creatures of magic and faerie is unmatched.
