Banishment PSION
With this power, the user can teleport a creature against its will to a pocket dimension and hold it there for as long as he chooses to continue spending 15 PSPs per round. The creature being banished must be within 15 ft. of the user. The pocket dimension is featureless, with a benign environment - hot or cold, light or dark, but not so much as to cause injury.
The banished creature returns to its original location as soon as the user stops paying the PSP cost. This boomerang feature won’t harm the creature. If the creature has access to the Astral or Ethereal planes, or if it can teleport between planes, it can try to return prior to the expiration of the power by rolling an Intelligence check at –3.
