Half certificate

Half certificates are used during the Shield of Arrav quest. When a player returns their half of the Shield to Curator Haig Halen of the Varrock Museum, they will recieve one half of the certificate, depending on whether they joined the Phoenix Gang or the Black Arm Gang. There are actually two different certificate halves, but they are identical in everything by appearance.

The player will recieve 2 copies of their half certificate, one of which must then be traded with a player from the other gang to recieve the other half. When combined, the player recieves a full certificate, which can be traded with King Roald to complete the quest and recieve a 600 coin reward.
