Trivia

 * This sword's name and appearance is a reference to Arthas's weapon, Frostmourne, from the Warcraft franchise.
 * As of 1.2.3, the Icemourne can in fact be obtained. The weapon's name, sprite, and overhead swinging animation work, however, the weapon has no statistics, thus attempting to use it as an actual weapon will not affect the enemy you are trying to attack.
