The Pendants of Planar Shifting were created by the Absalom Guard to allow the bearer to step into the Shadow Plane. It was granted to several party members who volunteered to investigate Shadow Absalom.
The pendants slowly gather planar energy as time passes. Once charged, the pendant allows the user to step into the opposite plane. So far, though, they have only allowed transport between the Shadow and Material Planes. It takes approximately three days to fully charge the pendant.
The user can activate its power by taking a step forward while concentrating on the other plane. After stepping forward, they "fall" through the ground, and pivot around a point in a 180, as though they were being flipped upside-down.
