This spell causes a ghostly, glowing hand, shaped from the caster's life force, to materialize within the spell range and move as the caster desires.
Any touch attack spell of 4th level or less that is subsequently cast by the wizard can be delivered by the spectral hand. The spell gives the caster a +2 bonus to his attack roll.
The caster cannot perform any other actions when attacking with the hand; the hand returns to the caster and hovers if the caster takes other actions. The hand lasts the full spell duration unless dismissed by the caster, and it is possible to use more than one touch attack with it. The hand receives flank and rear attack bonuses if the caster is in a position to do so.
The hand is vulnerable to magical attack but has an Armor Class of -2. Any damage to the hand ends the spell and inflicts 1d4 points of damage to the caster.
