Breezes seem to follow most sylphs wherever they go, but some sylphs are better able to control these winds than others. A sylph with this racial trait surrounds herself with swirling winds, gaining a +2 racial bonus to AC against nonmagical ranged attacks. The sylph can calm or renew these winds as a swift action. Once per day, the sylph can channel this wind into a single gust, making a bull rush or trip combat maneuver attempt against one creature within 30 feet. Whether or not the attempt succeeds, the winds are exhausted and no longer provide a bonus to the sylph's AC for 24 hours. This is a supernatural ability. This racial trait replaces air affinity.
