  • Fire Absorption. Whenever the lambent witchfyre is subjected to fire damage, it takes no damage and instead regains a number of hp equal to the fire damage dealt.
  • Fire Form. The lambent witchfyre can move through a space as narrow as 1 inch wide without squeezing. A creature that touches the lambent witchfyre or hits it with a melee attack while within 5 feet of it takes 5 (1d10) fire damage. In addition, the lambent witchfyre can enter a hostile creature’s space and stop there. The first time it enters a creature’s space on a turn, that creature takes 5 (1d10) fire damage and catches fire; until someone takes an action to douse the fire, the creature takes 5 (1d10) fire damage at the start of each of its turns.
  • Illumination. The lambent witchfyre sheds bright light in a 30-foot radius and dim light for an additional 30 feet.


  • Multiattack. The lambent witchfyre makes three blazing touch attacks.
  • Blazing Touch. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 13 (3d6 + 3) fire damage. If the target is a creature or a flammable object, it ignites. Until a creature takes an action to douse the fire, the target takes 5 (1d10) fire damage at the start of each of its turns. If a creature is slain by this attack, the lambent witchfyre regains hp equal to the damage dealt. The body of a creature slain by this attack turns to ash, along with any nonmagical items it was wearing or carrying. The creature can be restored to life only by means of a resurrection or wish spell.
  • Innate Spellcasting. The lava keeper’s innate spellcasting ability is Wisdom (spell save DC 17). It can innately cast the following spells, requiring no material components:


  • Multiattack. The lava keeper makes four slam attacks. Alternatively, it can use its Lava Lob twice.
  • Slam. Melee Weapon Attack: +13 to hit, reach 10 ft., one target. Hit: 25 (4d8 + 7) bludgeoning damage.
  • Lava Lob. Ranged Weapon Attack: +13 to hit, range 60/240 ft., one target. Hit: 21 (6d6) fire damage, and the target must succeed on a DC 19 Dexterity saving throw or take 10 (3d6) fire damage at the start of its next turn.
  • Fumarole (Recharge 5-6). The crater between the lava keeper’s shoulders erupts in a plume of fire, rock, and toxic smoke. Each creature within 60 feet of the lava keeper must make a DC 19 Constitution saving throw. On a failure, a creature takes 21 (6d6) bludgeoning damage and 21 (6d6) fire damage and becomes poisoned for 1 minute. On a success, a creature takes half the damage and isn’t poisoned. A poisoned target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. The eruption surrounds the lava keeper in a 20-foot-radius sphere of smoke, considered heavily obscured until the end of its next turn. A wind of moderate or greater speed (at least 10 miles per hour) disperses the smoke.


Inspired by the sight of a fearsome clockwork dragon, some kobolds with an understanding of engineering came together and forged their own dragon-like weapon of great power. Kobolds feel unstoppable when a war machine rolls along beside them, leading them to take bolder (and often more successful), risks.

A creature of pure blue fire trickles across the cavern floor, burning and devouring all except the stone.

Though its behavior is similar to oozes that infest subterranean areas, the lambent witchfyre is composed of living blue flame, not protoplasm. Like liquid fire, it flows along the ground, searching for food, which, in the case of the lambent witchfyre, is any organic matter that can burn.

Arcane or Alien Origins. The lambent witchfyre’s exact origins are unknown. Some sages speculate that it was an early attempt by a wizard to infuse life on the Material Plane with elemental essence.

Others theorize it is the disastrous byproduct of spell experimentation on an extra-planar creature.

Whatever the truth, these strange beings have multiplied and spread, posing a deadly hazard to those who explore the deep caves of the world.

Reproduction. When a lambent witchfyre has consumed enough organic material, it will seek an isolated place in which to reproduce. It then divides itself into two new lambent witchfyres, each starting with half the parent’s hit points. The offspring then go their separate ways, seeking more life to devour
