    Energy Cone

    Psychokinesis [see text]
    Level: Kineticist 3
    Manifesting Time: 1 standard action
    Range: 60 ft.
    Area: Cone-shaped spread
    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 a cone of energy of the chosen type, extending outward from your
    hand, that deals 5d6 points of damage to every creature or object within the
    area.

    Cold: A cone of this energy type deals +1 point of damage per die. The
          saving throw to reduce damage from a cold cone is a Fortitude save
          instead of a Reflex save.
    Electricity: Manifesting a cone 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 cone of this energy type deals +1 point of damage per die.
    Sonic: A cone of this energy type deals -1 point of damage per die and
           ignores an object<63>s hardness.

    This power<65>s subtype is the same as the type of energy you manifest.

    Augment: For every additional power point you spend, this power<65>s damage
             increases by one die (d6). For each extra two dice of damage, this
             power<65>s save DC increases by 1.
