Big event mystery box (Going Like Clockwork) was removed from RuneScape after an update, but still exists in-game for those who had obtained it. A big event mystery box can be obtained by converting 500 clockwork pieces or from handing in 8,500 pieces as part of the Going Like Clockwork event. Ironmen are unable to open these boxes. Contents[show] Rewards The box offers a total of five items when opened, a prismatic medium fallen star, and a mixture of four secondary and tertiary rewards. The box is destroyed after opening. Five free inventory spaces are required to open one.
