Phantom Blade

This spell creates a translucent, shadowlike, weightless area of magical force extending from the fingers of one of the caster's hands. This silent construct is blade-shaped. Its cutting edges inflict damage just as do those of a real sword. The caster wields the phantom blade as if proficient in the use of this weapon, at her normal THAC0

A phantom blade counts as a +2 magical sword for purposes of what it can hit (though it does not gain this attack or damage bonus), and cannot harm inorganic things (such as ropes) because it has no solid existence. Against living foes, it cuts and chills for 1d10 points of damage per successful strike. Against undead creatures, beings phasing into or out of the Ethereal Plane, or beings maintaining any simultaneous dual-plane existence, it gives a +4 bonus to the wielder's attack roll and causes 4d4 points of damage. A phantom blade is nonmetallic, nonmagnetic, and does not reflect light or conduct electrical energy. It cannot be dropped or torn from the caster's grasp, but it vanishes instantly if the caster desires.

A phantom blade is also effective against non-prismatic magical barriers (such as a wall of force) and fields (such as a minor globe of invulnerability). At each contact with such a barrier, roll 2d12. A maximum of one contact between the phantom blade and the barrier can occur per round. When the total of all such attacks exceeds the field's total points, the field or barrier is destroyed, along with the phantom blade. For purposes of determining when a barrier falls, a barrier has 10 points per spell Level: assign 70 points for effects with unknown level.
