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.

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.

False Appearance.

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

Innate Spellcasting.

The portrait's innate spellcasting ability is Intelligence (spell save DC 12). The portrait can innately cast the following spells, requiring no material components:

3/day each: counterspell, crown of madness, hypnotic pattern, telekinesis

Guardian Portrait
