Constructed Nature. An animated object doesn't require air, food, drink, or sleep. The magic that animates an object is dispelled when the construct drops to 0 hit points. An animated object reduced to 0 hit points becomes inanimate and is too damaged to be of much use or value to anyone.

Antimagic Susceptibility. The portrait is incapacitated while in the area of an antimagic field. If targeted by dispel magic, the portrait must succeed on a Constitution saving throw against the caster's spell save DC or become unconscious for 1 minute.

False Appearance. While the figure in the portrait remains motionless, the portrait is indistinguishable from a normal painting.
