Power Touch [Psionic]
Prerequisite: Str 13+, Psionic Fist.
Benefit: The character can make attacks of opportunity using any power he or she knows with a range of touch, if he or she has at least one hand free. The Power Touch attack of opportunity does not preclude the normal manifestation of a psionic power during the same round. The power used in conjunction with this feat costs a number of power points equal to its standard cost +2.
Normal: Attacks of opportunity do not involve casting spells or manifesting powers.
Special: Possession of the Quicken Power feat reduces the extra cost of Power Touch to 0 power points (the character still must pay the standard cost for the power used in the attack of opportunity).
