Earth Glide (Ex): A stone flyer can glide through stone, dirt, or almost any other sort of earth except metal as easily as a fish swims through water. Its burrowing leaves behind no tunnel or hole, and its passage does not create any ripples or other signs of its presence. A move earth spell cast on an area the stone flyer occupies pushes it back 30 feet but has no other effect.
Earth Glide Rider (Su): A stone flyer can extend its earth glide ability to include a rider and gear, up to a medium load.
Tremorsense (Ex): A stone flyer can automatically sense the location of any creature or object within 60 feet that is in contact with the ground.
Stone flyers usually hunt prey in packs, working in concert to bring down creatures that are traveling alone or lagging behind in a group. Once their quarry is unconscious or dead, they retreat into the earth or stone, taking their prey along to be consumed in safety, away from the site of the kill.
