Amulet Magic Detection and Location

While wearing this Quartz amulet, you are guided to a source of a casted spell. If you are within 1000 ft of the parent stone, and a person casts a spell within the same radius, you are directed by the stone to the source. The Quartz glows a color depending on the spell's school of magic. When you reach the source you see it have an aura of the same color. If there are multiple spells cast, the stone will glow white, but the source will still have the aura of the last spell casted school of magic.
