Fear Aura
The necromancer can surround him- or herself with an aura of fear similar to (though less powerful than) that of a lich. Any creature with fewer than 3 HD (or levels of experience) who views this palpable, black aura must make a saving throw vs. spells or flee in terror for 2-12 rounds. Creatures with more than 4 HD are entitled to a +4 bonus and only flee for 1-6 rounds if they fail the save. Beings of equal or greater hit dice than the necromancer are unaffected. Unlike the regular fear spell, this necromantic aura has a more gradual and numbing effect. Affected creatures are thus unlikely to drop carried items.
