Eye of Kilrogg is a core warlock ability learned at level 22. Casting summons a green, disembodied floating eye. It can move around while floating a yard or so from the ground, permitting the caster to see through it. While the eye is active, the caster is effectively in a channeling trance, so any interruption will cancel the eye. The eye has a slow fall effect so it will not take any type of fall damage. Tests suggest that the eye moves at approximately 200% of normal running speed, giving the eye an effective range of around 500 yards.
