Deep Impact

(Psionics Handbook 3.0, page 45, DnD 3.0)

[Psionic]

You can strike your foe with a melee weapon as if making a touch attack.

Prerequisite

Power Attack, Psionic Weapon, STR 13, base attack bonus +3 or more

Benefit

If you pay 5 power points per strike, you can resolve your melee attack with a weapon 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 melee attack. Your weapon remains "charged" for a maximum number of rounds equal to your Strength modifier +1, or until you make your next attack, whichever occurs first. If your attack misses, the power point expenditure is wasted.
