Cunning Opportunist.

The stone cursed has advantage on the attack rolls of opportunity attacks.

False Appearance.

If the stone cursed is motionless at the start of combat, it has advantage on its initiative roll. Moreover, if a creature hasn't observed the stone cursed move or act, that creature must succeed on a DC 18 Intelligence (Investigation) check to discern that the stone cursed isn't a statue.

Unusual Nature.

The stone cursed doesn't require air, food, drink, or sleep.
