Multiattack

The golem makes two slam attacks.

Slam

Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 13 (2d8 + 4) bludgeoning damage.

Poison Breath (Brimstone Infusion Only; Recharge 5-6)

The golem exhales poisonous fumes in a 30-foot cone. Each creature in that area must make a DC 16 Dexterity saving throw, taking 31 (9d6) poison damage on a failed save, or half as much damage on a successful one.
