The ability to convincingly take on counterfeit moods, emotions, voices, and lie convincingly over a period of time. This is not disguise or perform. A successful check will allow you to convey that you think or feel something that you do not.

Full impersonation requires successful a disguise check if you will be seen by the people you are trying to fool, and then an acting check to successfully perform in front of them. The acting check is at -1D if you are not well versed with your subject, -1D if those you are trying to fool are acquaintences of the original, -2D if they are well-acquainted.

Much of this skill can be overlayed with con, but that is generally thought of as a quicker fast-talk version whereas this is a more sustained illusion. Therefore the GM should determine if the action can use con and at what penalty.
