Weapon
Rare
This weapon was forged from iron ore sourced from a rich vein deep beneath the earth in the Shadowfell, the antithesis to the Feywild. Any non-magical light source that comes within 5 feet of this unsheathed weapon is extinguished. You gain a +1 to attack and damage rolls made with this magic weapon. When you hit a fey or creature with the Fey Ancestry trait with this weapon, the creature takes an extra 1d6 damage of this weapon's damage type plus 1d6 poison damage and must make a DC 15 Constitution saving throw. On a failed saving throw, the creature is poisoned until the start of your next turn. A fey slain by a cold iron weapon cannot be brought back to life by any means short of a wish spell.
