Mirrors of Purification

An array of shimmering steel mirror plates, connected by conductive cables and runic plates. Heavy and bulky, but still able to be set up in the field in an emergency
Over the course of a short rest, a creature can attempt a DC 20 Intelligence (Arcana) check to configure the mirrors, arranging them into a circle surrounding a point 15 ft. in diameter.
If the check succeeds, the mirrors can then be activated for 10 minutes. While active, any creature viewed reflected in one of the mirrors is seen as though the observer has truesight, and any telepathic communication to or from the creature is audible to anyone looking into one of the mirrors. The circle created by the mirrors cannot be entered by fiends, celestials, aberrations, elementals, fey or undead, as per the magic circle spell.
In addition, any creature can touch one of the runic plates and channel a 3rd level or higher spell slot. If they do so, any creature within the circle of mirrors is cleansed as though both remove curse and dispel magic were cast on them (at the level of the slot expended), if the creature is possessed the possession ends, and if the creature is a shapeshifter it is returned to its natural form.
After 10 minutes of activation, the mirror falls dormant, and cannot be activated until the next dawn.
