By casting this spell, a wizard can change a corpse's features to make it appear to be someone else. The caster must possess an accurate portrait of the individual to be duplicated, or must have a clear mental image of the person based on personal experience.
If animate dead is cast on the body, it can be animated to become a zombie that looks exactly like the copied person. The double is a mindless automaton, however, having all the characteristics of a normal zombie.
This spell may be cast on a creature that has already become a zombie. The wizard must successfully touch the zombie in combat, unless the zombie is controlled by the caster.
The material component of this spell is a drop of doppleganger's blood.
