Arcane Indicator

A small, silver disc with a sapphire embedded in the center. Intricate rings of runes surround the sapphire. The indicator is tuned to a specific spellcaster's arcane signature and the central gem will light up if the Indicator is within 100 feet of the spellcaster or within 300 feet of a spell that was cast by them.

Additionally, the indicator can cast locate creature targeting the spellcaster the indicator is tuned to. Casting locate creature in this way requires no material components and can identify a spellcaster in an alternative form if and only if their form was changed by a spell they cast themselves.
