The mark of grace is a token that was released 5th December 2013 and can be obtained on a semi-random basis by using the Rooftop Agility Courses. The tokens appear at specific locations on the ground during the course of a lap in varying degrees of frequency. Also, multiple marks of grace can spawn. The likelihood of obtaining a mark of grace increases as the difficulty of the rooftop agility course you are completing increases. For example, the rooftop course at Draynor Village, which only requires level 10 Agility, would have a substantially lower rate of obtainment as compared to the rooftop course at Ardougne, which in turn requires level 90 Agility. Thus, there is a benefit to using the more difficult courses.
