A void melee helm is a piece of Void Knight equipment that is obtained as a reward in the Pest Control minigame. It can be bought from a Void Knight for 200 commendation points, although a player must have at least level 42 Attack, Strength, Defence, Hitpoints, Ranged, and Magic, along with level 22 Prayer to buy and wear one.
The melee helm grants the player a 10% bonus towards Attack and Melee damage when worn with the Void knight top, robe and gloves. The Void knight mace and Void seal are not required for the bonus. It has the same stats as the other two helmets, and is considered to greatly benefit the training of the melee skills.
