Legacy of the Forlorn
Dark, Destructive Power
These foul, serrated horns are frequently used in the creation of weapons that cause bleed damage or drain constitution. When consumed as a material component during the casting of magic weapon (or greater magic weapon) the targeted weapon also gains the vicious special ability for the duration of the spell.
It is exceedingly rare to obtain the horns of a Cornugon, as not only are they terribly dangerous creatures, they tend to fade back to their home dimension when killed. Only powerful spellcasters, demon lords, and demigods have the power to summon and bind these creatures to the material plane, causing them to die permanently and physically, thus making it possible to harvest their horns.
