Power Touch

( Psionics Handbook 3.0, p. 0)

[Psionic]

You can make power-enhanced attacks of opportunity.

Prerequisite

Psionic Fist (PsH3_) , STR 13,

Benefit

You can make attacks of opportunity using any power you know with a range of touch, if you have 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.

Special

Possession of the Quicken Power feat reduces the extra cost of Power Touch to 0 power points (you still must pay the standard cost for the power used in the attack of opportunity).

Normal

Attacks of opportunity do not involve casting spells or manifesting powers.
