By linking the creature touched and the Plane of Shadow, you temporarily trade some of its traits for more potent ones belonging to creatures of that shady realm.

You grant the subject 5 temporary hit points for each of its Hit Dice (maximum 75). For the duration of the effect, the subject’s shadow grows larger than normal, and its movements are very slightly uncoordinated with those of the subject. An observer can notice this characteristic by making a DC 20 Perception check.
