All ogres can Phase-Shift, a method that while falling, can be used to transport themselves to safety using a special device.
Lady Gisela is known to have used phase-shifting during the ambush at Mount Everest, in Everblaze. She jumped off the edge of the mountain after being was surprised by Biana and was unable to keep fighting. Gethen, another member of the Neverseen, was taken captive because of her escape.
