A spider the size of an elephant, this dark blue arachnid rears up on its six hind legs to raise its barbed and razor-edged front claws.

Dismantle Armor (Ex) If a bebilith hits a foe with both claw attacks, it can attempt to peel away the target's armor and shield as a free action by making a CMB check. If the bebilith is successful, the target's armor and shield are torn from his body and dismantled, falling to the ground. Armor subjected to this attack loses half its hit points and gains the broken condition if the target fails a DC 25 Reflex save. The save DC is Strength-based.
Penetrating Strike (Su) A bebilith's natural weapons are treated as chaotic and magical for the purposes of penetrating damage reduction. Against creatures with the demon type, its natural weapons are also treated as cold iron and good.
Rot (Su) A bebilith's bite causes a horrible withering and weakening of the flesh, resulting in a hideous melting and foul rotting effect. This catastrophic withering begins on the round the creature is bitten and continues for another 4 rounds thereafter, for 5 rounds of withering in all. Each round the rot persists, the target must succeed on a DC 23 Fortitude save or take 2 points of Constitution damage. If the target makes two consecutive saving throws in a row, the effect is cured. Heal can also halt the rot effect. The save DC is Constitution-based.
The Abyss is a terrible place, yet even in this horrific realm there exist predators and wild beasts that prey upon the demonic horde—the bebilith being the most notorious, a creature evolved to hunt and slay demons.
Far more intelligent than its verminous shape would suggest, it is perhaps a blessing that the bebilith is such a focused and devoted hunter of demons, for had these dangerous outsiders more of a mind to conquer and expand empires, their ability to plane shift would make them a menace indeed. Although, as an outsider, the bebilith has no biological need to eat, it does enjoy the sensation of chewing on demonic flesh.
