The Duplication Potion is a potion that is used to create an exact duplicate of the drinker. The clothing worn is duplicated as well.
The potion is used to create a temporary duplicate of whomever drinks it. The duplicates are independent, but seemingly cannot be sustained for long periods of time. It has been shown to be used as a diversion.
In "Touched by a Demon", Jada Shields and Mel Vera used this potion to create a diversion when they went after the Finch siblings. The siblings saw the duplicates and shot arrows from crossbows at them, but they disappeared upon contact. The momentary confusion allowed Jada to catch them by surprise and take out the two witch hunters.
- The potion serves the same purpose as the power of astral projection in the original show, as both create a duplicate of the user.
