You can make psi-enhanced attacks of opportunity.
Benefit: To use this feat, you must expend your psionic focus. When you make an attack of opportunity, you can use any psi-power you know with a range of touch, if you have at least one hand free. Manifesting this psi-power is an immediate action. You cannot use this feat with a touch psi-power whose manifesting time is longer than 1 full-round action. Using this feat increases the PP cost by 4 levels.
Normal: Attacks of opportunity can be made only with mêlée weapons.
