Item from Curse of Strahd by Tracy & Laura Hickman, Chris Perkins / Wizards of the Coast
Plate armor blessed with divine energy, resting in Sergei von Zarovich's tomb in the crypts beneath Castle Ravenloft — one of the few holy relics that survived the castle's corruption.
Sergei's armor rests in his tomb in the crypts beneath Castle Ravenloft. It is a suit of plate armor that radiates holy energy — blessed at the time of its creation and maintained by the lingering sanctity of Sergei's spirit. Even in the deepest darkness of the castle, the armor gleams faintly. Wearing Sergei's armor provides protection against Strahd's necrotic abilities and the psychic terrors of the castle. It is a reminder of what Strahd destroyed — his brother's goodness, his brother's light — and wearing it into battle against the vampire lord carries a symbolic weight that even Strahd recognizes.
