Sword of the Lightbringer

Weapon (greatsword), artifact

Known as Phosphorus, the sword that the Lightbringer took up against the gods that precipitated the great fall was forged in the highest heavens from elements of the universe and the bones of an archangel who attempted to stop the Lightbringer from raising his hand against the creators.

The gleaming, reddish blade glows with a brilliant white light. The sword is large, being considered a greatsword in the hands of a Medium-sized being.

The blade grants you a +5 bonus to hit. It ignores immunity or resistance to slashing or critical hits. The sword deals 14 (4d6) additional slashing damage on a natural 20, and a second roll of natural 20 dismembers a victim’s limb, instantly cauterizing the wound so that it cannot be regenerated without additional magical assistance such as a heal spell.

The blade casts a bright pinkish light in a 10-foot radius and a dim light for an additional 20-foot radius.

The sword itself generates an aura of intense evil, and a successful DC 18 Charisma saving throw must be made by any non-lawful evil aligned bearer, lest they be unable to wield the weapon due to excruciating pain associated with its touch.
