Mad Necklace

The mad necklace is the item that jagex promised runescape players at the beginning of "Mad May". Originally this item was going to give up to 250k double experiance, but actually give 1.3x experiance. The item was released on 1 June, 2012 along with the update allowing members to sign up for the Evolution of Combat beta. In order to get the mad necklace you had to get it from Diango in Draynor Village.
