These tortured forms of what were once warriors are among the most terrifying things a necromancer can create, for a sword will cleave right through them, as through air itself. What inspires such fear is the thought that these beasts are invincible, a belief that is actually far from the truth. Because of this, a means was made by which the enchantments that drive these creatures could renew themselves through the very thing which threatened them. Special Notes: During battle, this unit can drain life from victims to renew its own health. Spirits have very unusual resistances to damage, and move quite slowly over open water._ This unit is able to move through solid stone walls.
