SRD:Telempathic Projection

You alter the subject’s mood, adjusting its attitude toward you by one step in a positive direction. For instance, an unfriendly creature can be made indifferent, or a hostile creature unfriendly. You can grant a +4 bonus on your own (or others’) Bluff, Diplomacy, Intimidate, Perform, or Sense Motive checks involving the affected creature.
