In-game description
"Ring of energy: 'The Victor'. Crafted by Drow mages of the Underdark, this weapon was used in an arranged battle between two rival houses. Each combantant was allowed to use a single magical item to aid his efforts. This ring was the weapon used by the victor of the contest, though he never laid hands on it. It was worn by his sibling and fired from the crowd, striking his opponent squarely in the back. Everyone witnessing agreed it was a brilliant interpretation of the rules."
