Many patrols pass her area after a while. If you can spike her and kill her before the other patrols show up, do so. Otherwise, work on pulling the patrols one by one. It will take more time, but is safer.
It is also possible to pull her with a bow while maintaining aggro without attracting other groups. Just hug the wall after you shoot. Make sure to wait for the Stone Shard Crag and Shambling Mesa to go down and flag your heroes back.
