The void knight mage helm is a member's only piece of Void knight equipment. It is obtained as a reward from the Pest Control and Conquestminigames and is sold for 240 thaler or by the Void Knights for 200 commendation points. It would take around 100 games on the easy boat, 67 on the medium boat, and 50 games on the hard boat of Pest Control to get this helm.
When worn with any three of four Void pieces (out of a Void Knight top, robe, gloves, and deflector), the helm increases magic accuracy by 3% and magic damage by 5%.[1]
It is possible to override the Void knight mage helm with Replica Void Knight equipment purchasable for 35,000 Loyalty Points at Solomon's General Store to have the retro void knight mage helm style. This retro style can be used to override your void equipment in the wilderness.
