  • Hellfire Touch. A non-fiend creature that touches the cendiary or hits it with a melee attack while within 5 feet of it takes 5 (1d10) fire damage and 4 (1d8) necrotic damage. With a touch, the cendiary can ignite flammable objects that aren’t worn or carried (no action required).
  • Illumination. The cendiary sheds bright light in a 30-foot radius and dim light for an additional 30 feet.
  • Legendary Resistance (3/day). If the cendiary fails a saving throw, it can choose to succeed instead.
  • Legion Focus. If the cendiary is affiliated with the Phlegethon legion, instead of the usual trait, the fire damage from its Fiery Touch and from targets set on fire by its crush and Rolling Flame are increased to 9 (2d8) fire damage and 5 (1d10) necrotic damage.
  • Magic Weapons. The cendiary’s weapon attacks are magical.
  • Wheeled Form. The cendiary treats any incline greater than 45 degrees as difficult terrain.


  • Multiattack. The cendiary makes one crush attack and one claw attack.
  • Crush. Melee Weapon Attack: +11 to hit, reach 5 ft., one target. Hit: 32 (4d12 + 6) bludgeoning damage, 11 (2d10) fire damage, and 9 (2d8) necrotic damage. If the target is a non-fiend creature or a flammable object, it ignites. Until a creature takes an action to douse the fire, the target takes 5 (1d10) fire damage and 4 (1d8) necrotic damage. The target must also succeed on a DC 19 Strength saving throw or be knocked prone.
  • Claw. Melee Weapon Attack: +11 to hit, reach 5 ft., one target. Hit: 15 (2d8 + 6) slashing damage.


The cendiary can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature’s turn. The cendiary regains spent legendary actions at the start of its turn.

  • Claw. The cendiary makes a claw attack.
  • Rolling Flame (Costs 2 Actions). The cendiary moves up to half its speed and flares with bright flame. The first time the cendiary comes within 10 feet of a non-fiend creature during this movement, that creature must succeed on a DC 16 Dexterity saving throw or ignite and be blinded until the end of the cendiary’s next turn. Until a creature uses its action to douse the fire, the ignited creature takes 5 (1d10) fire damage and 4 (1d8) necrotic damage at the start of each of its turns.


The cendiary takes the form of a great fiery wheel made of thick, rune-carved stone in which demonic arms and legs constantly appear and disappear, propelling the wheel forward. When these limbs don’t retreat within the wheel quickly enough, they are pulverized beneath the cendiary’s rolling weight, but the cendiary seems to feel no pain or concern at this loss and simply generates more appendages to push itself forward.

Endless Arson. Hellfire pours from the cendiary as it rolls, igniting anything it touches and providing a shimmering nimbus around it. This hellfire harms neither the cendiary’s rune-marked stone nor its flesh engines nor any nearby fiends. Since things of the mortal world share no such invulnerability, the cendiary leaves a trail of wildfires and ruin in its wake.

Constant Motion. The cendiary never stays in one place for long, rolling back and forth over the same scorched piece of ground if it needs to speak to others. Its communications are always disjointed, as its thought processes are several iterations ahead.

The cendiary is impulsive and darts off whenever a thought enters its head.

Legions. The cendiary typically leads fiends of the Phlegethon legion, or sometimes of the Acheron, Lethe, or Tartarus legions.

This massive stone wheel is alight with flickering flames and carved with many runes. Fiendish claws, hooves, and blank faces appear within its center, pushing the great wheel along with inhuman vigor.
