An adamant helm (h4) is a helmet that can be obtained from Level 2 Treasure Trails or bought from other players. It cannot be made using the Smithingskill. Players wear it for its unique design. It has stats identical to that of an adamant full helm, the only differences being that the helm is more expensive, has a different appearance, it cannot be smithed and can only be obtained through Treasure Trails. It requires 40 Defence to equip.
