Phantom Key
Wondrous item, uncommon
A key for hidden doors, a phantom key is made from bronze with a dull cracked stone set into its head. The key itself does not fit any conventional lock. When a phantom key is held aloft as part of a Search action to find hidden doors the crack in the stone reveals itself to be an eyelid, which opens to expose a fleshy eye that looks around the room granting a +2 bonus to the Search action. Moreover, when a phantom key’s tip is pressed against a secret door as part of a Use an Object action the door opens even if a special action is normally requires to open it (e.g., pulling a false book from a bookcase, pressing a hidden stud, speaking a secret work, etc.). When used to open a secret door that is locked, barred, or otherwise prevented from opening by magical or mundane means the phantom key crumbles to dust immediately afterward.
