Your senses are especially sharp, and can detect sudden movements and changes in the Winds of Magic, even if you are not a spellcaster. You immediately become aware of any spellcasting within your Perception in yards, although you cannot discern the nature of the magic and can tell only the rough direction of the source. Additionally, if you have the Second Sight Talent, or can otherwise perceive the Winds of Magic, you gain Advantage on any tests made to discern their whims or motions.
