    Psychokinesis [see text]
    Level: Psion/wilder 3
    Manifesting Time: 1 standard action
    Range: 40 ft.
    Area: 40-ft-radius burst centered on you
    Duration: Instantaneous
    Saving Throw: Reflex half or Fortitude half; see text
    Power Resistance: Yes
    Power Points: 5
    Metapsionics: Empower, Maximize, Twin, Widen

    Upon manifesting this power, you choose cold, electricity, fire, or sonic.
    You create an explosion of unstable ectoplasmic energy of the chosen type
    that deals 5d6 points of damage to every creature or object within the area.
    The explosion creates almost no pressure. Since this power extends outward
    from you, you are not affected by the damage.

    Cold: A burst of this energy type deals +1 point of damage per die. The
          saving throw to reduce damage from a cold burst is a Fortitude save
          instead of a Reflex save.
    Electricity: Manifesting a burst of this energy type provides a +2 bonus to
                 the save DC and a +2 bonus on manifester level checks for the
                 purpose of overcoming power resistance.
    Fire: A burst of this energy type deals +1 point of damage per die.
    Sonic: A burst 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). For each extra two dice of damage, this
             power’s save DC increases by 1.
