Energy Push
|
|||
|
|
|
|||
|
|
Psychokinesis [see text]
|
|||
|
|
Level: Psion/wilder 2
|
|||
|
|
Manifesting Time: 1 standard action
|
|||
|
|
Range: Medium (100 ft. + 10 ft./ level)
|
|||
|
|
Duration: Instantaneous
|
|||
|
|
Saving Throw: Reflex half or Fortitude half; see text
|
|||
|
|
Power Resistance: Yes
|
|||
|
|
Power Points: 3
|
|||
|
|
Metapsionics: Chain, Empower, Maximize, Twin
|
|||
|
|
|
|||
|
|
Upon manifesting this power, you choose cold, electricity, fire, or sonic.
|
|||
|
|
You project a solid blast of energy of the chosen type at a target, dealing
|
|||
|
|
it 2d6 points of damage. In addition, if a subject of up to one size
|
|||
|
|
category larger than you fails a Strength check (DC equal to the save DC of
|
|||
|
|
this power), the driving force of the energy blast pushes it back 5 feet
|
|||
|
|
plus another 5 feet for every 5 points of damage it takes. If a wall or
|
|||
|
|
other solid object prevents the subject from being pushed back, the subject
|
|||
|
|
instead slams into the object and takes an extra 2d6 points of damage from
|
|||
|
|
the impact (no save).
|
|||
|
|
|
|||
|
|
Cold: A blast of this energy type deals +1 point of damage per die (damage
|
|||
|
|
from impact remains at 2d6 points). The saving throw to reduce damage
|
|||
|
|
from a cold push is a Fortitude save instead of a Reflex save.
|
|||
|
|
Electricity: Manifesting a blast 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 blast of this energy type deals +1 point of damage per die (damage
|
|||
|
|
from impact remains at 2d6 points).
|
|||
|
|
Sonic: A blast of this energy type deals -1 point of damage per die (damage
|
|||
|
|
from impact remains at 2d6 points) 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 2 additional power points you spend, this power<65>s damage
|
|||
|
|
increases by one die (d6) and its save DC increases by 1. The damage
|
|||
|
|
increase applies to both the initial blast and any damage from
|
|||
|
|
impact with an object.
