Balefule Shadowport

You pull a creature through the plane of shadow, causing them to instantaneously swap positions. They both must be in range, and both must be touching a shadow. Objects carried by the subjects go with them (up to the creature's maximum load), but other creatures do not even if they are carried. The movement is instantaneous and does not provoke attacks of opportunity. If either creature succeeds it's WIS save, the powers effect is negated.
