Traits

Overheat. When the maschin-i-bozorg is reduced to 0 hit points, its power source overloads, briefly superheating its outer shell. Each creature within 10 feet of the maschin-i-bozorg must make a DC 16 Constitution saving throw, taking 7 (2d6) fire damage on a failed save or half as much damage on a successful one.

Actions

Multiattack. The maschin-i-bozorg makes two Poison Jab attacks.

Poison Jab. Melee or Ranged Weapon Attack: +6 to hit, reach 5 ft. or range 30/120 ft., one target. Hit:13 (4d4 + 3) piercing damage, and the target must succeed on a DC 16 Constitution saving throw or have the poisoned condition for 1 minute. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Steam Jet (Recharge 5–6). The maschin-i-bozorg emits scalding steam in a 30-foot cone. Each creature in that area must make a DC 16 Constitution saving throw, taking 28 (8d6) fire damage on a failed save or half as much damage on a successful one.

Bonus Actions

Crushing Stride. The maschin-i-bozorg moves up to its speed in a straight line. During this movement, it can enter Medium and smaller creatures' spaces. A creature whose space the maschin-i-bozorg enters must make a DC 15 Dexterity saving throw. On a successful save, the creature is pushed to the nearest unoccupied space out of the maschin-i-bozorg's path. On a failed save, the creature takes 10 (3d6) bludgeoning damage and has the prone condition.

If the maschin-i-bozorg remains in the prone creature's space, the creature also has the restrained condition until it's no longer in the same space as the maschin-i-bozorg. While restrained in this way, the creature, or another creature within 5 feet of it, can use its action to make a DC 15 Strength (Athletics) check. On a successful check, the creature is shunted to an unoccupied space of its choice within 5 feet of the maschin-i-bozorg.

Lore

The kagu-svirfneblin's most prized invention is the maschin-i-bozorg: a dome-shaped, steam-powered battle construct propelled by a multitude of wheels along its flat underside. Maschin-i-bozorgs typically act as guardians and sentries, tirelessly patrolling the sites they're assigned to protect. Each machine obeys the commands of its creator.
