In-game description
"Cloak of Reflection: Vorn Druidslayer crafted this cloak and used it with great success in his campaign to eliminate the druids from all the woods south of Baldur's Gate. His campaign ended abruptly when he encountered a flock of wyverns, who were attracted by the cloak's sheen. They killed Vorn and used the cloak to cover their nest, serving to protect their young during electrical storms."
