The rug is incapacitated while in the area of an antimagic field. If targeted by dispel magic, the rug must succeed on a Constitution saving throw against the caster's spell save DC or fall unconscious for 1 minute.
While it is grappling a creature, the rug takes only half the damage dealt to it, and the creature grappled by the rug takes the other half.
While the rug remains motionless, it is indistinguishable from a normal rug.
