Benefit: As long as you have both Mind Knight path powers, you can manifest both Mind Knight path powers at the same time as a single standard action. Any time you manifest call weaponry, you may select one other 1st level power you know; you may manifest that power using Martial Power as if it were a Path power, as long as the attack is made using the weapon summoned. In addition, when using the Mind Knight maneuver, you gain a +1 competence bonus on the attack rolls for every four psychic warrior levels you have.
