SPELL-WRAITH-LESSER-GREATER-KNIGHT-LORD

These spells summon forth undead wraiths, the souls of fallen adventurers, to inhabit the corpses of recently killed foes. Wraiths sap their foes strength with potent chills, and cannot be harmed by the cold. As the skills of a necromancers advance, they are capable of calling on more powerful spirits to form their wraiths, eventually calling the souls of great warriors and long-dead lords to their aid.
