Rod of mirrors

A rod of mirrors gives the holder the ability to make an insubstantial round mirror at its end, two feet (0.6m) in diameter, which lasts for eleven minutes, and when the holder looks through the back, sees as the spell true seeing. The holder is also immune to all gaze attacks and illusion effects coming from the other side of the mirror. The first of these rods was created by the wizard Glendar, and each is worth around 40,000 gold pieces.
