The subject becomes slowed and you become hasted (as per the slow and haste spell effects). Each round on its turn, the subject may attempt a new saving throw to end the effect. This is a free action that does not provoke attacks of opportunity.
If the subject makes its saving throw, you become slowed for 1 round (no saving throw).
