Impersonation

This spell must be cast upon a willing subject, who immediately assumes the appearance of a person of his choice. The subject becomes the same height, sex, and race of the target person selected, even speaking with the same voice, and gesturing with the same mannerisms-the impersonator is indistinguishable from the original in all outward appearances.

However, the impersonator does not acquire the original's memories or abilities, and cannot automatically speak the original's language. Furthermore, if the impersonator does anything that is out of character for the original, anybody present who knows the original is allowed a saving throw vs. spell. Those making a successful save see through the illusion and realizes that an impostor has taken the original's place.

The material component is a drop of blood, lock of hair, or cherished possession belonging to the original individual.
