  1. ^ Mod Ryan. Prosper Perk. 6 February 2017. "It sounds like luck isn't in your favour. The rates aren't that high, but they do differ depending on the skill that you train. It's worth noting that your chances are not increased if you already own any clue scrolls. As an example, if it tries to give you an easy clue but you already own own then it'll stop there."*
