Pendant of Mystic Warding

A pendant of mystic warding allows the wearer to monitor their surroundings for the use of magic. The wearer is constantly aware of the presence of magical auras within 30 feet; this is identical to the 1st-round effect of ''detect magic. If they concentrate, the wearer can sharpen this magical sense as if using detect magic'', allowing them to sense the strength, location, and school of magic involved in each aura. The wearer can concentrate indefinitely.

A pendant of mystic warding can only be used by a character who possesses the ability to cast arcane spells.
