Expedition to Castle Ravenloft
The Sunsword is a magic bastard sword whose blade is a crystalline form of glassteel, while the hilt and guard are forged of platinum. The blade glows with a dim blue light until it is brought within 30 feet of undead, increasing its radiance to a brilliant sapphire.
The weapon’s blade and hilt were sundered long ago. While separated from its hilt, the blade of the Sunsword resembles an ordinary longsword.
This blade is sought by the Lightbringers and is weapon vampires fear.
