Mysterious Runed Rock

The Mysterious Runed Rock is an entry in the Agility level-up guide, which appeared on or before the 10 October 2016. It requires level 95 and has the icon of a yellow "jump-over" type shortcut.

Currently, it is not known what the runed rock is - be it a well-hidden easter egg, a teaser for a future update, or merely a mistake.
