I want to do some mining at the Chasm mine north of Al-Kharid, but the lvl-14 scorpions keep attacking me. So I wonder how high combat lvl I have to get before they stop auto attacking me? And also in general with other beasts, whats the differens between their level and yours when they stop attacking? Because I know at some level they won't attack you anymore... It just have to get somewhat higher then theirs... Thanks, jiggii.
