A Black helm (h3) is a helmet can be obtained by completing a level 1 clue scroll, or from other players. As with all treasure trails and black armour, this cannot be made with the Smithing skill.
It has the same defence bonuses as a black full helm. It requires 25 Defence to equip, and is bought for its unique design.
The design on this helmet features a yellow and red checkered box area.
Before the Treasure Trails update, the helm was able to be put into a house alone, but it now requires the entire set.
