Special Traits

  • Flyby. The fulminar doesn’t provoke an opportunity attack when it flies out of an enemy’s reach.
  • Essence of Lightning. Bolts of lightning course around the fulminar’s body, shedding bright light in a 5- to 20-foot radius and dim light for an additional number of feet equal to the chosen radius. The fulminar can alter the radius as a bonus action.
  • Lightning Form. The fulminar can enter a hostile creature’s space and stop there. It can move through a space as narrow as 1 inch wide without squeezing. A creature that touches the fulminar or hits it with a melee attack while within 5 feet of it takes 7 (2d6) lightning damage.


  • Multiattack. The fulminar makes three attacks: one with its bite and two with its claws.
  • Bite. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 14 (2d8 + 5) piercing damage and 7 (2d6) lightning damage and the target can’t take reactions until the end of the fulminar’s next turn.
  • Claw. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 12 (2d6 + 5) slashing damage and 7 (2d6) lightning damage.
  • Lightning Shackles (Recharge 5–6). The fulminar magically creates three sets of shackles of lightning, each of which can strike a creature the fulminar can see within 60 feet of it. A target must make a DC 16 Dexterity saving throw. On a failure, the target takes 18 (4d8) lightning damage and is restrained for 1 minute. On a success, the target takes half the damage but isn’t restrained. A restrained creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.


Aerial Felines. Fulminars are creatures composed of semisolid elemental matter and roughly shaped like large feline predators.

Cloud Giant Allies. Fulminars were either created or first summoned by powerful cloud giant sorcerers. They can also be found in the company of djinnis, silver dragons, and other creatures strongly connected to the element of air. It is unclear whether they have their own motives or are directed by a higher, elemental power.

Lightning-Fast Slayers. Thanks to their speed, stealth, and a strange magical ability to entrap creatures with shackles of lightning, fulminars are extremely versatile, serving as spies, assassins, and shock troops.

Elemental Nature. A fulminar doesn’t require air, food, drink, or sleep.
