Complete Psionic
You can manifest powers that affect targets lurking in coexistent planes and extradimensional spaces whose entrances fall within the power's area.
Benefit: You must expend your psionic focus to manifest a transdimensional power. A transdimensional power has its full normal effect on incorporeal creatures, creatures on the Ethereal Plane or the Plane of Shadow, and creatures within an extradimensional space in the power's area. This includes ethereal creatures, creatures that are blinking or shadow walking, manifested ghosts, and creatures within the extradimensional space of a rope trick, portable hole, or other portable extradimensional space.
You must be able to perceive a creature to target it with a transdimensional power, but you do not need to perceive a creature to catch it in the area of a burst, cone, emanation, or spread.
Using this feat does not increase the power point cost of the power.
Normal: Only force effects can affect ethereal creatures, and no Material Plane attack affects creatures on the Plane of Shadow or in an enclosed extradimensional space. There is a 50% chance that any power other than a force effect fails against an incorporeal creature.
