Big Mo is a travelling salesman and businessman overseas. He is located in a random location each day, and is only available during May 2015. Once per day during May, he will offer you a clue scroll for 50 coins. The tier of clue scroll is random each day but the chance of getting a selected clue increase with each clue.
Each day at midnight (00:00) GMT, Big Mo will move to a new location. His location is hinted by the official Old School RuneScape Twitter feed.
