A faint ripple in the air suggests a hazy and vaguely humanoid vapor moving with terrible swiftness.

Improved Tracking (Ex)
An aerial servant takes no penalty on Survival checks when moving its full speed and gains a +10 bonus on Survival checks to track.
Natural Invisibility (Su)
This ability is constantly in effect, even when the aerial servant is attacking, and is not subject to invisibility purge. Against foes that are unable to see invisible creatures, it gains an additional +20 bonus on Stealth checks when moving, or +40 when stationary. On the Astral Plane or the Ethereal Plane, an aerial servant gains concealment (20% miss chance) rather than invisibility.
Wind Blast (Su)
Once every 1d4 rounds, as a standard action, an aerial servant can release a blast of wind in an 80-foot line, dealing 8d8 points of bludgeoning damage (Reflex DC 22 half). Medium or smaller creatures that fail their saving throws are knocked prone and pushed 1d4 × 5 feet away. The save DC is Constitution-based.
