Multiattack. The golem makes either two slam attacks or one slam attack and it uses its engulf ability.

Slam. Melee Weapon Attack: +8 to hit, reach 5ft., one target. Hit: 15 (2d6 + 8) bludgeoning damage plus 7 (2d6) fire damage.

Engulf. The golem moves up to its speed. While doing so, it can enter Large or smaller creatures' spaces. Whenever the golem enters a creature's space, the creature must make a DC 18 Dexterity saving throw. On a successful save, a creature can choose to be pushed 5 feet back or to the side of the golem and takes 7 (2d6) fire damage. A creature that chooses not to be pushed suffers the consequences of a failed saving throw. On a failed save, the golem enters a creature's space, and the creature takes 21 (6d6) fire damage and is engulfed. The engulfed creature can't breathe, is restrained, and takes 31 (9d6) fire damage at the start of each of the golem's turns. When the golem moves, the engulfed creature moves with it. An engulfed creature can try to escape by taking an action to make a DC 18 Strength check. On a success, the creature escapes and enters a space of its choice within 5 feet of the golem.

Ashen Breath (Recharge 6). The golem exhales burning ash in a 15-foot cone. Each creature in that area must make a DC 18 Dexterity saving throw, taking 31 (9d6) fire damage on a failed save, or half as much damage on a successful one. The area is heavily obscured. This effect lasts for 1 minute or until a wind of moderate or greater speed (at least 10 miles per hour) disperses it.
