SRD:Psychokinetic

Psychokinetic: Upon command, a psychokinetic weapon glows from the inside with lethal psionic energy. The energy does not harm the hands that hold the weapon. Such a weapon deals an extra 1d4 points of damage on a successful hit. This extra damage is ectoplasmic in nature and is not affected by damage reduction. Bows, crossbows, and slings bestow this ability upon their ammunition.
