This glass orb is 6" in diameter, cool to the touch and virtually indestructible.
As a bonus action the orb may be moved up to 60 feet in the air, where it hovers in place until recalled. The orb may be controlled without being able to see it, up to 500 feet away. The owner of the orb will be aware of any living creature or treasure within 30 feet of the orb. As an action the owner may look through the orb at the surrounding area. The orb is capable of pushing against forces of up to 100 lbs, and resisting being pushed by forces of up to 115 lbs.
Whispering a command word causes an effect, only one may be active at a time:
"Subtlety" causes the orb to turn invisible, but it cannot be moved when invisible.
"Luminance" causes the orb to glow as if the Light spell was casted on it.
"Grievance" causes the orb to emit a deafening tone that can only be heard by enemies of the orb's owner.
"Mobility" causes the orb to shed any detrimental effects on it, and if it's stuck it immediately moves to the nearest open space.
