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

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.
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.
Environment any (Plane of Air)
Aerial servants are deadly hunters native to the Plane of Air, though they often wander through planar portals to the Ethereal Plane and sometimes roam the Astral Plane as well. They are generally called to the Material Plane as bounty hunters or assassins, using their natural invisibility and near-faultless tracking skills to pursue their quarry and then strike unseen. They typically scatter enemies with blasts of wind before closing in to strangle their prey. While an aerial servant is easy to confuse with an invisible stalker, the former is far more dangerous, and those who misidentify the creature may not live to regret underestimating it.
Those who call aerial servants must be careful to assign them tasks that are possible for them to complete, as the temperamental elementals occasionally track down and attack their callers if they fail at their assigned tasks.
