Special Traits

  • Alien Anatomy. When an attacker scores a critical hit against a denizen of Leng, it has a 50% chance to treat it as a normal hit instead. It also takes only half damage from a rogue’s sneak attack. A denizen of Leng also gains advantage on saving throws against polymorph spells or any other effect that would change its shape.
  • Deflect Spells. A denizen of Leng is immune to spells which specifically affect undead.
  • Dimensional Regeneration. A denizen of Leng regains 5 hit points at the start of its turn. If it takes force or radiant damage, this trait doesn�t function at the start of the denizen’s next turn. The denizen dies only if it starts its turn with 0 hit points and does not regenerate. If killed, a denizen’s body dissolves into nothingness in 1d4 rounds, leaving behind its gear. It is rumored that slain denizens simply reform new bodies in Leng, conjured out of the mutable essence of the dimension of dreams, rather than being permanently slain.


  • Multiattack. A denizen of Leng makes two claw attacks.
  • Claws. Melee Weapon Attack: +9 to hit, 5 ft. reach. Hit: 14 (2d8 + 5) slashing damage, and 14 (4d6) psychic damage.
  • Confusion (Recharge 6). Each creature in a 10-foot-radius sphere is affected by a confusion spell (save DC 16).


These eerie denizens travel the universe from their strange homeland of Leng, walking uncontested only when they disguise themselves as humans by wearing loose-fitting robes and wrappings about the head and face. Under these disguises, they have horned brows, clawed fingers, mouths full of tentacles, and crooked goatish legs with cloven hooves. A denizen of Leng weighs 200 pounds and stands roughly 5-1/2 feet tall.

Dimensional Raiders. Many scholars have argued over where the otherworldly realm of Leng lies – some believe it can be found among the Outer Planes, while others are convinced it can only be reached via a dimension of dreams. The denizens of Leng can travel to other planes freely, and often do so in strange, black ships, constantly seeking new breeds of slaves or trading rubies for unusual services or magical treasures. At other times, their visits are much more violent, focusing on abducting victims for use as slaves or worse.

On Leng, these denizens have long fought a war against that realm�s monstrous spiders, a war that sometimes spills over into other worlds.
