Project Thoughts (Proficiency)

This deceptively named proficiency does not involve mental communication or telepathy in any way. Instead, it is as close to a physical attack as a body gets on the Astral Plane. Simply put, a character with this skill projects her extraneous, random thoughts upon the astral form of another, thus slowing her down as she is caught in the mire of mental drag (see "Racing Through Nothing: Astral Movement").
It works like this: If a body has this proficiency and makes a successful skill check, she can project her thoughts around any figure within sight. If the target has a lower Intelligence score than the projector of the thoughts, the target is slowed down to a stop, held in place (able to act, but not able to move from that point in "space"). If the Intelligence score of the target is equal to the projector, the target's movement rate is halved. In any case, this ability affects only movement, not other activities like combat, spellcasting, etc.
The effect lasts as long as the projector devotes her full concentration. The target can make Intelligence checks each round (starting the round after the initial effect) to attempt to break the hold. The target must remain within the sight of the projector or the hold is automatically broken.
