Mythic Spell-Like Abilities (Su)

Three times per day when a mythic Leng spider uses a spell-like ability, it can expend one or more uses of its mythic power to duplicate the mythic version of that spell. It treats its mythic rank as its mythic tier for the purpose of augmenting spell-like abilities.

Poison (Su)

  • Bite—injury; save Fort DC 27; frequency 1/round for 6 rounds; effect 1d4 Con plus confusion for 1 round; cure 2 consecutive saves.

A Leng spider’s venom causes flesh to blister and rot away and the mind to experience vivid and horrific hallucinations—these visions cause the poisoned creature to react in an unpredictable manner, as if confused. The hallucination element of this poison is mind-affecting. The save DC is Constitution-based.

Slimy Webbing (Ex)

By expending one use of its mythic power as a swift or immediate action, a mythic Leng spider can alter the composition of the webs created by their web and web strand special abilities. Such webs have DR 15/–, 30 hp, and are immune to fire damage. This ability lasts 1 round, but the webs created by the mythic Leng spider during that round retain these properties for 24 hours.

Transdimensional Perception (Su)

A mythic Leng spider can perceive the Ethereal Plane, the Plane of Shadow, and the Dimension of Dreams (unless Leng is also currently inside the Dream Dimension) from Leng and the Material Plane. By expending one use of its mythic power it can phase its melee and bite attacks across the dimensional barriers to attack the inhabitants of those planes. By expending two uses of mythic power, a Leng spider can attempt to entrap a target with its web strand and pull it into the same plane as the mythic Leng spider, provided the planes are coterminous. If the attack hits, the target receives a DC 24 Will save to resist being pulled across the planar barrier. The save DC is Charisma-based.

Web Strand (Ex)

A mythic Leng spider can shoot a strand of adhesive webbing at a single target as a primary ranged touch attack with 90-foot reach. The strand deals no damage on a hit, but can be used to entrap and pull. If the target successfully avoids being entrapped, they are still attached to the web strand and cannot move away from but they can move around and toward the Leng spider. As a standard action, a creature can rip the filament free with a DC 30 Strength check. A caught creature can also attempt to escape a filament by making a DC 30 Escape Artist check. A filament is AC 14 (touch AC 12), has 15 hit points, and has DR 20/—. An application of universal solvent dissolves the adhesive and releases the creature caught by the filament. A mythic leng spider can have only one web strand active at a time. A mythic Leng spider can expend one use of its mythic power and for one round make iterative ranged attacks with the web strand until it hits a target. It may do so while in melee and does not provoke attacks of opportunity.

Web Weaponry (Ex)

A Leng spider is talented at using its webs to construct masterwork weapons. This technique of weapon creation allows the spider to effectively create a flail or bolas by attaching a heavy object such as a rock or chunk of metal to a cord of webbing. The spider attaches one end of this webbing to a leg and can then wield the weighted cord as a masterwork flail or a masterwork bolas. It can only wield one such weapon at a time—it must use its other legs to walk. If a Leng spider drops or loses a web weapon, it can create a new one as a full-round action, provided it has access to heavyweight objects of the correct size (such as loose rocks or skulls).


Environment any
Organization solitary, council (3 or 5, always odd)
Treasure double

This immense purple spider has a leg span of nearly forty feet and a hideously bloated body, yet still moves with fluid grace.

Leng spiders are intelligent, carnivorous spiders with hideously bloated bodies, though they can move with terrifyingly fluid grace. An adult has a legspan of 20–30 feet or occasionally more, but smaller (younger) specimens are common. An adult weighs 1-3 tons. Since they never stop growing, a few are far larger. They vary in color from deep purple to lambent orange.

Leng spiders are sly and design traps for their prey. These can be elaborate and often involve treasure as bait. They are clever enough to let some adventurers live after finding the treasure, to entice further visitors to their mountain lairs.

They delight in preying on humanoid egos and spring traps when a would-be treasure-seeker is most confident. Leng spiders thrive on being underestimated.

These murderous beasts are not terrestrial at all but hail the mysterious plateau of Leng beyond the Dimension of Dreams. Both in their home realms and in their nests and networks in the mortal world, Leng spiders have a complex society and are readily able to wage war on those who infringe on their territory. Unless in their homes, they rarely fight to the death and will retreat if severely wounded to plot their revenge.

Leng spiders build complex lairs out of their webs, many of which serve a dual purpose as temples to the eldritch gods they venerate. Most Leng spiders worship deities of the Elder Mythos, such as Hastur, Nyarlathotep, or Yog-Sothoth, among others.
