A witch with this hex can create a magic sensor that she can see through.
Effect: This functions as per the spell arcane eye. If the witch has the coven hex, all other witches within 10 feet who also have the coven hex can see through this sensor as well, although the witch that created it still controls it. The witch can use this eye for a number of minutes per day equal to her level. These minutes do not need to be consecutive, but they must be spent in 1-minute increments.
