The Void Knight archers are the only helpers during the Pest queen boss fight that can hit Pest drones. Because Elite defilers can attack them, the defilers should be attacked to distract them as soon as they appear. As soon as they killed the Pest Drones, these archers will attack the Pest Queen which can be very handy. The Void Knight archers are the most valuable helpers during the fight. They have 500 life points, just like Elite defilers.
