    Psychic Crush

    Telepathy [Mind-Affecting]
    Level: Psion/wilder 5
    Manifesting Time: 1 standard action
    Range: Close (25 ft. +5 ft./2 levels)
    Target: One creature
    Duration: Instantaneous
    Saving Throw: Will partial; see text
    Power Resistance: Yes
    Power Points: 9
    Metapsionics: Empower, Maximize, Twin

    Your will abruptly and brutally crushes the mental essence of any one
    creature, debilitating its acumen. The target must make a Will save with a
    +4 bonus* or collapse unconscious and dying at -1 hit points. If the target
    succeeds on the save, it takes 3d6 points of damage.

    Augment: For every 2 additional power points you spend, this power’s damage
             increases by 1d6 points.


    * Due to the way saves are handled in NWN, this has been implemented as a
      lowered DC instead.
