A spell used to transfer the appearance of a dead person to a willing target
Skin transfer is a powerful spell to transform one's appearance. While it hurts a lot, it's hard to differentiate the real from the fake person. Not only do they take their appearance, they also get the most dominant memories at the time of the death of the deseased.
The voice, mannerisms, etc. can still give away the identity.
The appearance of the targeted person is changed, it is near flawless, but it does not change the voice.
