Void seal

The Void seal is a piece of Void Knight equipment reward in the Pest Control or activity. It can be bought from a Void Knight for 10 commendation points, although a player must have at least 42 Attack, Strength, Defence, Constitution, along with 22 Prayer to buy and wield one. This item is worn in the amulet spot. The seal, when the player clicks the 'operate' function, will inflict about 10 hitpoints of damage upon nearby Pests. The seal has eight charges. Once its 8 charges are used, it dissolves. It can only be utilised in Pest Control games, and does not contribute to the 50 hitpoints that must be inflicted. It is useless in normal combat except for the bonus. Most people consider the seal not worth buying.
