    Energy Ray

    Psychokinesis [see text]
    Level: Psion/wilder 1
    Manifesting Time: 1 standard action
    Range: Close (25 ft. + 5 ft./2 levels)
    Effect: Ray
    Duration: Instantaneous
    Saving Throw: None
    Power Resistance: Yes
    Power Points: 1
    Metapsionics: Chain, Empower, Maximize, Split Psionic Ray, Twin

    Upon manifesting this power, you choose cold, electricity, fire, or sonic.
    You create a ray of energy of the chosen type that shoots forth from your
    fingertip and strikes a target within range, dealing 1d6 points of damage,
    if you succeed on a ranged touch attack with the ray.

    Cold: A ray of this energy type deals +1 point of damage per die.
    Electricity: Manifesting a ray of this energy type provides a +2 bonus on
                 manifester level checks for the purpose of overcoming power
                 resistance.
    Fire: A ray of this energy type deals +1 point of damage per die.
    Sonic: A ray of this energy type deals -1 point of damage per die and
           ignores an object’s hardness.

    This power’s subtype is the same as the type of energy you manifest.

    Augment: For every additional power point you spend, this power’s damage increases by one die (d6).
