A ring that slightly reduces any thunder damage sustained by the wearer. The stone residing in its center evokes the image of a flashing bolt of lightning, and it has the ability to weaken the power of thunder. However, it cannot completely protect the wearer from thunder attacks, nor absorb their energy. Although some believe that wearing the spark ring will help them avoid being struck by lightning, it unfortunately has no such effect.

Lightning is a sudden electrostatic discharge during an electrical storm between electrically charged regions of a cloud (called intra-cloud lightning or IC), between that cloud and another cloud (CC lightning), or between a cloud and the ground (CG lightning).
Thunder is the sound caused by lightning. Depending on the distance and nature of the lightning, thunder can range from a sharp, loud crack to a long, low rumble (brontide).
