The Void knight seal is a member's only piece of Void Knight equipment reward earned through Pest Control and Conquestminigames. It can be bought from a Void Knight for 10 commendation points, and has no requirements to be worn. This is also a reward from the first Void Knight quest Quiet Before the Swarm. Additionally, each pest killed has a chance to drop a void seal and a bonus commendation point. When that happens a message appears saying: "You have earned a bonus Commendation and a Void Knight seal for defeating the invading void pest!"
The seal has eight charges. Once its 8 charges are used, it dissolves. They can be used to teleport to the Void Knight Outpost, at the cost of one charge.
While playing Pest Control, the player can click the 'rub' function to inflict 800~1000 damage upon nearby pests, costing one charge. This cannot be used to damage portals and does not contribute to the 5,000 life points that must be inflicted. When used, the player will get a message in their chatbox saying "You unleash the power of the Void Knights!"
