Players can obtain a master clue scroll from the following methods: * By bringing one each of the easy, medium, hard and elite clue scrolls to Watson at his house, which is located south of the estate agent at the Hosidius House. It should be noted that if you have an incomplete master scroll and attempt to obtain a new scroll, Watson will take all lower tier scrolls but NOT give you a master scroll until either you complete the original scroll or discard it. * As a potential reward from completing any easy, medium, hard or elite treasure trails, with the chances of obtaining them being 1/50, 1/30, 1/15, and 1/5 respectively.
