Psychokinesis [see text]
|
|||
|
|
Level: Psion/wilder 3
|
|||
|
|
Manifesting Time: 1 standard action
|
|||
|
|
Range: 120 ft.
|
|||
|
|
Area: 120-ft. line
|
|||
|
|
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 release a powerful stroke of energy of the chosen type that deals 5d6
|
|||
|
|
points of damage to every creature or object within the area. The beam
|
|||
|
|
begins at your fingertips.
|
|||
|
|
|
|||
|
|
Cold: A bolt of this energy type deals +1 point of damage per die. The
|
|||
|
|
saving throw to reduce damage from a cold bolt is a Fortitude save
|
|||
|
|
instead of a Reflex save.
|
|||
|
|
Electricity: Manifesting a bolt 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 bolt of this energy type deals +1 point of damage per die.
|
|||
|
|
Sonic: A bolt 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.
