Horn of the Exalted Dead: This horn is a necromantic version of the horn of Valhalla, except that it raises up the spirits of dead warriors (rather than summoning berserkers from Valhalla) to fight for the owner. According to Kazerabet's Art of Necromancy, the horn may be enchanted by a necromancer or death priest to bind the spirits of dead warriors into service. The instrument is typically inscribed with the names of 2-7 individuals whom the owner must call before blowing the horn.
Each of these spirits can be summoned from the netherworld once per week to serve the owner. Regardless of their level of experience in life, the spirit warriors now serve in combat as 5th-level fighters, having AC 4 and 30 hp each (THACO 16). Each is armed with a sword and spear. As spirits, they are immune to all weapons of less than +1 enchantment and unaffected by cold, poison, paralyzation, sleep, hold, and charm spells. They can be turned as wraiths.
After they have been summoned, the spirit warriors remain for up to an hour or until they have been forced to return to the netherworld by being reduced to 0 hp or being subjected to spirit release or dispel evil. In any event, these spirits are not destroyed and can still be called by the hom after another week has passed.
The horn of the exalted dead can be used by either necromancers, death priests, or common warriors, though only members of the former two professions may use the necromantic item with impunity. If the owner is a warrior, upon sounding the horn for the first time, his or her name will be magically appended to the list on the instrument. After the warrior dies, his spirit will be bound to the hom, and subsequent owners will be able to summon that warrior from the netherworld, too. Nothing short of a wish (or the destruction of the hom) can erase the fighter's name from the ranks of the undying on the hom. (4,000 XP).
