Dead Ringer

You create a duplicate of yourself from material conjured from the Shadowfell. The duplicate appears in an unoccupied space that you can see within 10 ft of you with half of your maximum hitpoints, and is indiscernible from you including appearance, voice and clothing but has none of your equipment. The duplicate stands or lies in place and can appear to be living or dead but is otherwise motionless and unresponsive.

As long as you are on the same plane of existence as your duplicate you can use an action to assume direct control of it as if it were your own body and perceive through its sense as if they were your own. Whilst controlling the duplicate, your original body is blinded, deafened and incapacitated but any damage done to you appears on your duplicate's body. Your duplicate can't cast spells but can use any of your other skills and abilities. As a free action you can relinquish control of the duplicate leaving it to appear living or dead.

If the duplicate drops to 0 hitpoints the spell ends but the duplicate body remains until you cast this spell again causing any previous duplicates to vanish.
