Vorpal Sword

Type: Physical Manipulation, Duration: Sustained, Damage: Physical, Range: Touch, Drain: (Force/2)+2
Effect: This spell may be used by the caster, or to empower someone within his reach. It creates a glowing sword made of pure mana. Treat it as though it was a bladed weapon (DV: (Magic/2 round up) + Spellcasting Hits, AP: - Charisma/2 round down, Reach: 1) and use the appropriate skill tests to attack, parry or defend against. Unlike a normal sword, this weapon is not powered by the strength of it's wielder's muscles, but rather by the power of it's caster's magic. It thus does not gain additional damage based on strength as most melee weapons would, however it does still gain the usual net hits to damage from the melee combat test. The damage from the sword is entirely magic based and thus bypasses Immunity to Normal Weapons. Counterspelling my be added to the defender's resistance dice pool. A +2 reach version my be cast by adding another 2 points to the drain value of this spell.

This spell was likely originally created by either a Norse or Japanese tradition mystic adept, or just a mage with a penchant for sword fighting, but has likely since spread and gained it's current name along the way.

[Edit] Updated to reflect the fact that the sword glows.
