Immutable Form. The golem is immune to any spell or effect that would alter its form.

False Appearance. While the golem remains motionless, it is indistinguishable from an inanimate statue.

Limited Magic Immunity. The golem is immune to spells of 4th level or lower. It has advantage on saving throws against all other spells and magical effects except as follows. A transmute rock to mud spell slows it (as in the slow spell) for 1 minute, with no saving throw, while transmute mud to rock heals all its lost hit points.

Magic Weapons. The golem's weapon attacks are magical.

Multiattack. The golem can make three attacks: one with its bite and two with its claws.

Bite. Melee Weapon Attack: +12 to hit, reach 5 ft., one target. Hit: 18 (2d10 + 7) piercing damage.

Claw. Melee Weapon Attack: +12 to hit, reach 5 ft., one target. Hit: 14 (2d6 + 7) slashing damage.

Petrifying Breath (Recharge 5-6). The golem exhales petrifying gas in a 30-foot cone. Each creature in that area must succeed on a DC 19 Constitution saving throw. On a failed save, a target begins to turn to stone and is restrained. The restrained target must repeat the saving throw at the end of its next turn. On a success, the effect ends on the target. On a failure, the target is petrified until freed by the greater restoration spell or other magic.
