By Print artist: Utagawa Kuniyoshi (歌川国芳) –, Public Domain,

The Tsuchigumo lives in the Japanese Alps. The name means “ground spider”, likely due to perceived physical traits that were later exaggerated or embellished.

Bebiliths are enormous, predatory, arachnid demons that hunt other demons. A bebilith has a body the size of a plow horse, with legs spanning more than 14 feet. It weighs more than two tons.

They understand but do not speak Abyssal. Their telepathy allows them to communicate silently with one another.

A bebilith attacks any creature it sees. It usually picks one target and concentrates its attacks on that opponent, using its webs to isolate the target from its comrades. Should the bebilith become overwhelmed by tougher opponents, it often attempts to bite one or more of its victims and retreats, allowing its poison to do its work.

A bebilith’s natural weapons, as well as any weapons it wields, are treated as chaotic-aligned and evil-aligned for the purpose of overcoming damage reduction.

Poison (Ex): Injury, Fortitude DC 24, initial damage 1d6 Constitution, secondary damage 2d6 Constitution. Bebilith venom is highly perishable, losing its potency and becoming inert, foul-smelling goo almost as soon as it comes into contact with air. The save DC is Constitution-based.

Rend Armor (Ex): If a bebilith hits with both claw attacks, it pulls apart any armor worn by its foe. This attack deals 4d6+18 points of damage to the opponent’s armor. Creatures not wearing armor are unaffected by this special attack. Armor reduced to 0 hit points is destroyed. Damaged armor may be repaired with a successful Craft (armorsmithing) check.

Web (Ex): A bebilith can throw a web up to four times per day. This is similar to an attack with a net but has a maximum range of 30 feet, with a range increment of 10 feet. This attack is effective against targets of up to Gargantuan size. The web anchors the target in place, allowing no movement.

An entangled creature can escape with a DC 24 Escape Artist check or burst the web with a DC 24 Strength check. The check DCs are Constitution-based. The web has
14 hit points and hardness 0. There is a 75% chance that the webbing will not burn if any sort of fire is applied to it (check each round).

Plane shift (Su): This ability affects only the bebilith. It is otherwise similar to the spell (caster level 12th).

Skills: A bebilith has mottled coloration that gives it a +8 racial bonus on Hide checks.

Characters with ranks in Knowledge (the Planes) can learn more about bebiliths. When a character makes a successful skill check, the following lore is revealed, including the information from the lower DCs. Those who recognize the creature’s ancestry can use Craft (poisonmaking) to learn more.

Knowledge (the Planes)


This arachnoid creature is a bebilith, a type of demon. This result reveals all outsider and tanar’ri traits.


Bebiliths are highly predatory creatures that enjoy hunting other demons, but aren’t picky and won’t pass up the opportunity to hunt other creatures.
30 A bebilith tends to focus on one opponent at a time. If it cannot single out an enemy, it will use bite the creature and retreat, waiting while its poison weakens the victim. In addition to its poisonous bite, a bebilith possesses the ability to rend a foe’s armor, destroying it.
Craft (poisonmaking)


A bebilith’s venom, while extremely potent, is also highly perishable and loses its potency upon contact with the air almost instantaneously.
