    Disable

    Telepathy (Compulsion) [Mind-Affecting]
    Level: Psion/wilder 1
    Manifesting Time: 1 standard action
    Range: 20 ft.
    Area: Cone-shaped emanation centered on you
    Duration: 1 min./level
    Saving Throw: Will negates
    Power Resistance: Yes
    Power Points: 1
    Metapsionics: Extend, Twin, Widen

    You broadcast a mental compulsion that convinces one or more creatures of
    4 Hit Dice or less that they are disabled. Creatures with the fewest HD are
    affected first. Among creatures with equal Hit Dice, those who are closest
    to the power’s point of origin are affected first. Hit Dice that are not
    sufficient to affect a creature are wasted.
    Creatures affected by this power believe that they have somehow been brought
    to the brink of unconsciousness and must act accordingly.

    Augment: For every 2 additional power points you spend, this power’s range
             increases by 5 feet and its save DC increases by 1.
    In addition, for every additional power point you spend to increase the range and
    the save DC, this power can affect targets that have Hit Dice equal to 4 + the
    number of additional points.
