Mirror of opposition

Mirrors of opposition were a type of enchanted mirror with a duplicative effect.

Powers
Whenever a creature was reflected in a mirror of opposition, it would conjure a duplicate of them that sought to kill the original creature. These duplicates were exact, possessing the same items and powers as the original, including those of a magical nature. If destroyed they would disappear alongside their duplicated belongings. Destroying a duplicate's original also had the same outcome.

History
In the mid–14 century DR, the first level of Undermountain had a hall of mirrors in which a mirror of opposition was installed.

In 1368 DR, a mirror of opposition hung within the the Blue Alley.
