The Benicoff TV

The Benicoff TV is one of several Objects of Power Jesse encounters in the main story, finding it possessed by the Hiss in the Panopticon. While normally the object is only known to float around, when Jesse tries to cleanse it, it warps the cell that its in to where it becomes much bigger, levitating larges chunks of concrete and creating an entirely different room that remains there for the rest of the game. When Jesse cleanses it of the Hiss's influence, she is able to bind it and gains the power to levitate.
