A black full helm (bugged) is an item used in The Void Stares Back. It has been modified by Korasi to record the player's movements. When worn along with a Black platebody (bugged) and Black platelegs (bugged), the player can infiltrate the Black Knights' Fortress. The helm has the same bonuses as a normal Black full helm. It should not be confused with the Black knight helm, an unequippable item used in King's Ransom.
During the quest, the player is required to take off the helm by Captain Gilroy of the Black knights. The helm is lost (does not go into inventory) when this happens.
