Aura strong evocation (evil) CL 20th; Slot weapon; Price —; Weight 10 lbs.
Stormblade is a Large +6 unholy longsword—as with all slashing weapons, Stormblade becomes a vorpal weapon in the hands of a balor. The body of a creature decapitated by Stormblade is disintegrated if the decapitation results in death, and heals the wielder of 100 points of damage.
Stormblade melts into blood and mist if its long-dead nascent demon lord owner is restored to life.
