Provided the wizard is conscious and within the area of effect, he will be made aware of any spellcasting conducted in that area. The particular spell cast is not made known, but the location of the wizard is, precisely if the wizard is familiar with the area, generally otherwise. The notification is sufficient to disrupt casting in progress, unless it is consciously suppressed before casting (if suppressed, the wizard does not realise the scan was triggered). Material component is a handful of crystal dust.
