  • Camouflage. The sphierlex is able to blend in with almost any environment, giving it advantage on all stealth checks.


  • Multiattack. The sphierlex makes 4 attacks with its claws and one with its bite, or uses its wings or uses its breath weapon.
  • Claw. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 5 (1d4+3) slashing damage
  • Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 7 (1d8+3) piercing damage.
  • Toxic Cloud Breath Weapon (recharge 6). The sphierlex breathes out a thick cloud of poisonous gas. It fills an area 30 feet in diameter from the mouth of the creature. Any creature that starts its turn in the cloud or that enters the cloud on its turn must make a Constitution save (DC 14) or take 10 (3d6) poison damage. The cloud remains for 1 minute before dispersing. The sphierlex is immune to its own poison.
  • Wings. The sphierlex can flap its wings in a bizarre, hypnotizing pattern. All creatures within 30 feet of the sphierlex that can see the wings must make a Wisdom save (DC 13) or be stunned until the end of the sphierlex’s next turn.


The sphierlex is a very slender, lizard-like creature. It has 10 legs, five on each side of its torso, and crawls much like an insect. Small ridges of bone line the creature’s back, extending all the way to its snout. Its scales are very small and range from a dull gray to dark brown in color. Many rows of serrated teeth line its small, long snout. Though flightless, the sphierlex possesses four long, thin wings. These are used in battle to bemuse and confound its prey.

Wide-Ranging. Sphierlex live in almost any uninhabited region, easily able to blend in with their environs, though they prefer sandy, dry, or hot environs. They are solitary hunters, never in the company of their own kind. They are migratory creatures, moving vast distances in search of prey. However, they do hole up in natural caves for several months, or at least until they deplete the local food sources. At which point they leave the den for more fertile pastures. If they encounter another of their kind, they treat it as a prey animal.

No Family. Once in a lifetime, females spawn, laying their eggs in remote locations. The creature is always on the move when laying eggs; one egg is laid and the sphierlex moves on to lay another egg. Their eggs are generally buried a few inches underground or otherwise hidden beneath rocks, brush, and the like. The males, following the scent, unearth the eggs, fertilize

Ambusher. These beasts are quite intelligent. They watch their prey carefully, stalking it. Once they are sure of the direction that their intended prey is traveling, they camouflage themselves in rocks, fallen trees, or even patches of earth. When the prey is almost upon them, they release their breath weapon and close in for the kill.
