Fell Shot( Psionics Handbook 3.0, p. 46)
You can strike your foe with a ranged weapon as if making a touch attack.
If you pay 5 power points per shot, you can resolve your ranged attack as a touch attack for purposes of assessing your foe's Armor Class. You must decide whether or not to pay the cost prior to making the ranged attack. Your bullet, bolt, or arrow remains "charged" for a maximum number of rounds equal to your Dexterity modifier + 1, or until you make your next attack, whichever occurs first. If your attack misses, the power point expenditure is wasted.
