This finely woven carpet resembles a carpet of flying and will give off magical radiations if detected for. 

The character seating himself or herself upon it and giving a command will be surprised, however, as the rug of smothering will tightly roll itself around that individual and suffocate him or her in 3-6 rounds. 

The rug cannot be physically prevented from so wrapping itself, and the rug can be prevented from smothering its victim only by the casting of any one of the following spells: alter reality, animate object, hold plant, wish.
