The gold headband is a members only item worn on the head. There are no requirements to wear it and it is purely cosmetic, meaning it does not offer any combat bonuses.
To obtain it, the player can either trade with another player or receive one as a medium Treasure Trail reward. The Gold headband can be stored in the Costume room of a player-owned house. The headband can be used as a requirement for a hard clue scroll emote clue.
