Publication:Dread Codex/New Spells/Necrosword

Necrosword creates a 3-foot longsword of swirling energy that springs forth from your hand. The blade strikes as a melee touch attack and drains negative energy, inflicting 1d8 points of damage +1 point per 2 caster levels (maximum +10) against corporeal and incorporeal undead opponents. The blade is also bone-chillingly cold and inflicts half this damage as cold damage against living opponents.
